| The Nucleon Axial Coupling from QCD Evan Berkowitz (Forschungszentrum Jülich) The axial coupling of the nucleon, gA = 1.2723(23), is the strength of the nucleon's coupling to the weak axial current of the Standard Model. It dictates the rate at which neutrons decay into protons, the strength of the attractive long-range force between nucleons, and other features of nuclear physics. To disentangle Standard Model effects from new physics, precision tests of the Standard Model in nuclear environments require a quantitative understanding of nuclear physics rooted in QCD, the theory of quarks and gluons. The nucleon axial coupling has long been considered a critical benchmark for lattice QCD, and yet proved substantially more challenging to calculate than expected. I will describe and give an update to our recent percent-level calculation, gA = 1.271(13), and how our method differs from existing approaches. | ||

| Spin foams and background independent renormalization Dr. Sebastian Steinhaus (Perimeter Institute) Spin foams models are a background independent path integral approach to quantum gravity. In a nutshell, they can be seen as generalized lattice gauge theories, where the sum over geometries is encoded in a sum over group-theoretic data encoding the shape and face areas of polyhedra. In this talk I will give a brief introduction to spin foams and outline the construction for 4D quantum gravity. After reviewing some of their achievements I will discuss open outstanding issues and how these are addressed by renormalization. To do so I will introduce a framework for renormalizing background independent theories and how numerical methods are used to implement this scheme in practice. | ||

| Towards reconstructing the quantum effective action of gravity Dr. Benjamin Knorr (RU Nijmegen) I will present a new method to constrain the quantum effective action of gravity, inspired by recent results from causal dynamical triangulations (CDT). After a short introduction to CDT, I will start from a parameterisation of the effective action to calculate correlation functions for observable quantities. Matching these correlators to CDT data allows to reverse-engineer the couplings which describe the effective dynamics. As a concrete example, the autocorrelation of spatial volume fluctuations is considered. The comparison to CDT data suggests the existence of non-local interaction terms, which might have interesting phenomenological consequences for the interpretation of dark energy. | ||

| Gravitational Waves and Numerical Relativity Prof. Harald Pfeiffer, AEI Potsdam Abstract: The past two years have witnessed the advent of gravitational wave (GW) astronomy led by the Advanced LIGO and Virgo GW detectors, which have announced the observation of six binary black holes and one binary neutron star. GW astronomy relies on knowledge of the gravitational waveforms for a variety of reasons: To design the search strategies to detect gravitational waves, to measure masses, spins and tidal parameters of the coalescing compact objects, and also to test general relativity and to search for signatures of physics beyond classical general relativity. This talk summarizes the GW observations of LIGO and Virgo, and elucidates the interplay between data-analysis and waveform modeling. Particular emphasis will be paid to numerical relativity simulations, the only means to compute the gravitational waves emitted during the genuinely nonlinear and dynamic late inspiral and merger phase of compact object binaries. | ||

| On Spectral Properties of Spin-Boson Models Talk by Markus Lange Abstract: We consider a quantum mechanical system, which is modeled by a Hamiltonian acting on a finite dimensional space with degenerate eigenvalues interacting with a field of relativistic bosons. Provided a mild infrared assumption holds, we prove existence of the ground state eigenvalues and ground state eigenvectors using operator theoretic renormalization. We show that the eigenvectors and eigenvalues are analytic functions of the coupling constant in a cone with apex at the origin. | ||

| Spin memory effect and charges of the extended BMS algebra Speaker: Dr. David A. Nichols Room: SR 5 Helmholtzweg 4 Abstract: The gravitational-wave memory effect is an unusual prediction of general relativity characterized by an asymptotically constant change in the gravitational-wave strain between early and late times. It produces a measurable effect for freely falling observers (a lasting displacement), it is generated by fluxes of matter and gravitational waves near null infinity, and it is closely related to the symmetry group of asymptotically flat spacetimes, the Bondi-Metzner-Sachs (BMS) group. Recently, however, there have been proposals that the symmetries of asymptotically flat spacetimes are the larger, extended BMS algebra. There are finite charges related to these additional symmetries, and changes in these charges produce a new kind of memory effect called spin memory. In this talk, I will introduce and discuss the gravitational-wave memory effect, the spin memory, and the conserved charges related to the extended BMS algebra. I will also discuss how these memory effects could be measured from binary black hole mergers using ground- and space-based gravitational-wave detectors. | ||

| Simulating Binary Neutron Star Mergers in the Multi-Messenger Era Prof. Bruno Giacomazzo (University of Trento) Abstract: I will present results of fully general relativistic magnetohydrodynamic (GRMHD) simulations of binary neutron star mergers performed by my group in Trento. Thanks to the detection of GW170817 the new era of multi-messenger astrophysics has finally started. That detection provided us with evidence for the first time of the connection between binary neutron star mergers and short gamma-ray bursts as well as other electromagnetic signals, such as the predicted kilonova emission. Numerical simulations of binary neutron stars have helped in the study of the dynamics of these systems during the last phases of inspiral, merger, and post-merger evolution. In this talk I will present results of numerical simulations performed by my group in Trento and that focused in particular on the effects that magnetic fields may have both in powering short gamma-ray bursts and in affecting the gravitational wave emission. | ||

| Gravitational waves, black holes and their interaction: a global perspective Prof. J. Frauendiener, University of Otago Abstract: It is well known that gravitational waves interact in a non-linear way. This makes it difficult to describe them rigourously. The cleanest description is based on a certain conformal invariance of the Einstein equations — a fact which was established by R. Penrose and was used by H. Friedrich to prove several important global results for general relativistic space-times. The so called conformal field equations implement this conformal invariance on the level of partial differential equations. They provide various well-posed initial (boundary) value problems for use in different situations. The talk will give a computational perspective on the non-linear interaction of plane gravitational waves and also present preliminary results of a simulation of the behaviour of an initially spherically symmetric black hole under the impact of a gravitational wave burst. | ||

| Promotionsverteidigung: Nichtlineare Wechselwirkungen von Gravitationswellen Disputation von Stefan Palenta Nach einer ausführlichen Einleitung zu Gravitationswellen und nichtlinearen Effekten werden die Grundlagen einer neuen Lösungstechnik für das charakteristische Anfangswertproblem kollidierender ebener Gravitationswellen vorgestellt. Unter Annahme einer ebenen Symmetrie vereinfachen sich die Einstein-Gleichungen zur Ernst-Gleichung. Diese nichtlineare partielle Differentialgleichung wird im Rahmen der inversen Streumethode zunächst in ein überbestimmtes System linearer Differentialgleichungen und schließlich in ein Riemann-Hilbert Problem überführt. Mehrdeutigkeiten in dessen Lösung führen zur Konstruktion einer ganzen Familie exakter Raumzeiten, welche die eigentliche Lösung des Anfangswertproblems verallgemeinert. Deshalb kann die vorgestellte Technik auch als eine interessante Methode zur Lösungserzeugung dienen. Das Verfahren wird anhand der Erweiterung der Szekeres-Klasse von Wellenkollisionsraumzeiten demonstriert. Die dadurch erhaltene Lösung beinhaltet als Grenzfall einen neuen Typ impulsiver Gravitationswellen mit zirkularer Polarisation. | ||

| An Introduction to asymptotically safe Quantum Gravity Stefan Lippoldt (University of Heidelberg) Abstract: This talk will start with a short reminder on the renormalization group concept, and how this is implemented in the flow equation. In the following I will relate this idea to quantum gravity (QG) focussing on the failure of perturbative QG. In the main part of this talk I will discuss how the asymptotic safety (AS) scenario may provide us with a non-perturbative way of quantizing gravity. For this I will look at pure QG, demonstrating that the inclusion of the famous Goroff-Sagnotti counter term of perturbative QG seems to pose no problem for the AS conjecture. Finally I will be concerned with the inclusion of matter. In particular I will have a glimpse at the intimate interplay of gravity and matter in the ultraviolet. | ||

The applicability of hydrodynamics in the critical region of the phase diagram is shortly discussed. | ||

| Disputation: Discontinuous Galerkin Methods for General Relativistic Hydrodynamics Disputation of Marcus Bugner Die Implementierung und Überprüfung einer neuen numerischen Methodik zur allgemeinrelativistischen Simulation von Neutronensternen wird vorgestellt. Zur Behandlung der hydrodynamischen Variablen wurde sowohl eine diskontinuierliche Galerkin-Methode, als auch ein Finite-Volumen-Verfahren auf krummlinigen Gittern implementiert. Zusätzlich wurden dem Code Techniken zur Schockerkennung und -behandlung hinzugefügt. Diese Bestandteile wurden in umfangreichen Tests validiert. Hierbei wurden numerische Fehler in der Massenerhaltung, in der Einhaltung von physikalischen Zwangsbedingungen und im Vergleich mit analytischen Lösungen betrachtet. Die zugehörigen Konvergenzordnungen aller Methoden wurden untersucht. Dabei wurde eine Konvergenzordnung ∼ 2 bei aktiver Schockbehandlung und mögliche Konvergenzordnungen > 2 für die reine diskontinuierliche Galerkin-Methode festgestellt. Weiterhin wurde bestätigt, dass die numerische Einhaltung der metrischen Identitäten essentiell für die Massenerhaltung in Fluiddynamik-Simulationen ist. Mit Hilfe der reinen diskontinuierlichen Galerkin-Methode konnten physikalische Systeme ohne Schocks, wie etwa die Michel-Bondi-Akkretion, erfolgreich simuliert werden. Bei Neutronensternsimulationen hingegen wurden numerische Instabilitäten an der Sternoberfläche und ein Verlust der Konvergenz beobachtet. Erst eine aktive Schockbehandlung erlaubt die stabile und numerisch konvergente Simulation von statischen, rotierenden oder oszillierenden Neutronensternen. Dank der vorgestellten Modifikationen des bamps Codes ist dieser nun in der Lage, die frontale Kollision zweier Neutronensterne zu simulieren. Neben der Extraktion des zugehörigen Gravitationswellensignals wurde die Simulation genutzt, um das nahezu ideale Skalierungsverhalten der Rechenzeit von bamps aufzuzeigen. The Talk will be held in English | ||

| A c-Theorem for Two-dimensional Boundaries and Defects talk by Andy O'Bannon (University of Southampton) Abstract: I will present a proof for a monotonicity theorem, or c-theorem, for a three-dimensional Conformal Field Theory (CFT) on a space with a boundary, and for a higher-dimensional CFT with a two-dimensional defect. The proof is applicable only to renormalization group flows that preserve locality, reflection positivity, and Euclidean invariance along the boundary or defect, and that are localized at the boundary or defect, such that the bulk theory remains conformal along the flow. The method of proof is a generalization of Komargodski’s proof of Zamolodchikov’s c-theorem. The key ingredient is an external “dilaton” field introduced to match Weyl anomalies between the ultra-violet (UV) and infra-red (IR) fixed points. Reflection positivity in the dilaton’s effective action guarantees that a certain coefficient in the boundary/defect Weyl anomaly must take a value in the UV that is larger than (or equal to) the value in the IR. This boundary/defect c-theorem may have important implications for many theoretical and experimental systems, ranging from graphene to branes in string theory and M-theory. | ||

| Renormalization of SU(2) Yang-Mills theory with Flow Equations Alexandre Efremov (CPHT, Ecole Polytechnique, Palaiseau) We give a proof of perturbative renormalizability of SU(2) Yang–Mills theory in four-dimensional Euclidean space. The main motivation is to present a proof which does not make appear mathematically undefined objects (as for example dimensionally regularized generating functionals). A large part of the proof is dedicated to bounds on massless correlation functions and to the restoration of the Slavnov-Taylor identities. | ||

| (Some aspects of) operator algebras and quantum physics Prof. Andrés Reyes Lega Universidad de los Andes Bogotá, Kolumbien Abstract After briefly reviewing some of the basic notions of operator algebras that are relevant for the algebraic approach to quantum physics, I will discuss two classes of C*-algebras that are relevant in quantum physics, namely the Weyl algebra and the CAR (or fermionic) algebra. Then, three examples of recent applications will be discussed: (i) the use of the GNS construction in the study of entanglement in systems of identical particles (ii) the Sorkin-Johnston state for scalar fields in curved spacetimes and (iii) the relation between the Shale-Stinespring theorem and the topology underlying the (thermodynamic) phase transition in the Ising model. | ||

| Catching ghosts — from unitarity to asymptotic safety Chris Ripken (Radboud University Nijmegen) Abstract: Higher derivative theories arise naturally in the context of effective quantum field theories. However, it is well-known that these theories generally are non-unitary. The purpose of this talk is two-fold. First, I will show why higher derivative theories are unitarity violating by discussing its Euclidean analogue, which is called Reflection Positivity. Secondly, we will consider a way of dealing with higher-derivative theories by means of the Renomalization Group. A requirement similar to Asymptotic Safety may be imposed on the infrared side of the RG trajectory to provide a unitary EFT. | ||

| Gauge theories at finite fermion density: avoiding the sign problem in the canonical formulation Prof. Urs Wenger (Uni Bern) Abstract: In this talk I discuss gauge theories at finite fermion density which, in general, suffer from a fermion sign problem. One approach to the sign problem is to use the canonical formulation where the fermion number is fixed. Using Wilson fermions on the lattice the canonical sectors of the theories can be obtained directly from transfer matrices explicitely defined through the fermion Dirac operator. As a first example, I consider supersymmetric SU(N) Yang-Mills theories in 0+1 dimensions and present some results concerning the moduli space of these theories. As a second example, I discuss QCD in the heavy-dense limit and show how the sign problem is avoided in the strong coupling limit. Finally, as a third example, related to heavy-dense QCD, I construct a cluster algorithm for the 3-state Potts model which solves the sign problem completely, even away from the strong coupling limit. | ||

| Shnol type Theorem for the Agmon ground state Dr. Siegfried Beckus (Technion Haifa) The celebrated Shnol theorem 4 asserts that every polynomially bounded generalized eigenfunction for a given energy E∈R associated with a Schrödinger operator H implies that E is in the L2-spectrum of H. Later Simon 5 rediscorvered this result independently and proved additionally that the set of energies admitting a polynomially bounded generalized eigenfunction is dense in the spectrum. A remarkable extension of these results hold also in the Dirichlet setting 1, 2. It was conjectured in 3 that the polynomial bound on the generalized eigenfunction can be replaced by an object intrinsically defined by H, namely, the Agmon ground state. During the talk, we positively answer the conjecture indicating that the Agmon ground state describes the spectrum of the operator H. Specifically, we show that if u is a generalized eigenfunction for the eigenvalue E∈R that is bounded by the Agmon ground state then E belongs to the L2-spectrum of H. Furthermore, this assertion extends to the Dirichlet setting whenever a suitable notion of Agmon ground state is available. 1 A. Boutet de Monvel, D. Lenz, and P.

| Ernst Mach and Machian effects in general relativity Prof. Jiri Bicak, Charles University (Prague) Abstract: I shall start with some remarks on Ernst Mach (1838-1916), who spent many years at the University in Prague and at the Vienna University. I briefly recall his and Einstein's ideas on the origin of inertia and their influence on the construction of general relativity. I mention the direct experiment verifying relativistic dragging/gravitomagnetic effects - the Gravity Probe B; the results were summarized only recently. I shall then turn to several specific general-relativistic problems illustrating the gravitomagnetic effects: the dragging of particles and fields around a rotating black hole, dragging inside a collapsing slowly rotating spherical shell of dust, linear dragging in a static situation, and the way how Mach's principle can be formulated in cosmology. A more detailed discussion will be devoted to the dragging effects by rotating gravitational waves. | ||

| Worldline Formalism and noncommutative QFT Sebastián Franchino-Viñas (La Plata / TPI) Abstract: The Worldline Formalism possesses great advantages in comparison with a Feynman's diagram analysis of a quantum field theory. On the other hand, noncommutative quantum field theories are probably one of the most important candidates to be an effective theory of quantum gravity. We then show how to implement the worldline formalism in noncommutative theories. The result is a master formula for the 1-loop effective action that is applied to a number of scalar models — among them the Grosse-Wulkenhaar model a model with some unusually kind properties of renormalization. As a byproduct we find an expression for the small propertime expansion of general nonlocal operators' Heat Kernel. | ||

| Wave equations in curved backgrounds: numerical applications to black-hole quasi-normal modes and AdS/CFT correspondence Rodrigo Panosso Macedo (FSU Jena) Abstract: We present a spectral representation of solutions to relativistic wave equations formulated on a Schwarzschild-black-hole background. We first consider an asymptotically flat spacetime and, after performing a Laplace transformation on the wave equation in question, we present an algorithm for obtaining all ingredients of the desired spectral decomposition, including quasi-normal modes, quasi-normal mode amplitudes as well as the jump of the Laplace-transform along the branch cut. The work explains extensively this procedure and includes detailed discussions of relevant aspects, such as the contribution of infinity frequencies modes to the early time response of the black hole and its relation to the QNM-amplitudes grow’s rate. In a second part, we employ the same strategy to study the solution of wave equations on an asymptotically AdS background. The system models the response of the chiral magnetic effect due to continuous quenches induced by time dependent electric fields via AdS/CFT correspondence and here, we focus on the possibility of considering the asymptotic growth rate of the amplitudes as a well defined notion of initial time scale for linearized systems. | ||

| Astrophysical jets: a new numerical approach to force-free electrodynamics Dr. Federico Carrasco (CONICET, Ciudad Universitaria Cordoba): Force-Free Electrodynamics (FFE) is a non-linear system of equations modeling the evolution of the electromagnetic field in the presence of a magnetically dominated relativistic plasma. This configuration arises on several astrophysical scenarios of interest such as pulsars or active galactic nuclei. In this talk, I will present a new numerical implementation of FFE around a Kerr black hole, which reproduce standard results regarding jet formation and energy extraction by means of a truly stationary electromagnetic configuration. The novelty of our approach is three-folded: i) We use the multi-block technique (1) to represent a domain with S2x R+ topology within a stable numerical scheme. ii) We employ as evolution equations those arising from a covariant hyperbolization of the FFE system (3), which we have developed using the generalized symmetric hyperbolic formalism of Geroch (2). iii) We implement stable and constraint-preserving boundary conditions, which represents an outer region given by a uniform magnetic field aligned/misaligned with the symmetry axis.

Perturbation theory organizes quantum field theory calculations as expansions in Feynman graphs. Each Feynman graph stands for a multi-dimensional integral over a differential form which is a rational function with integer coefficients. We report on the mathematical structures of the numbers and functions which arise from these integrals. We also indicate how these structures can be used to perform (some) quantum field theory calculations to very high order. | ||

| Non-commutative quasicrystals II Felix Pogorzelski, Technion Haifa, Israel Abstract: This is a continuation of last week's talk of quasicrystals in possibly non-commutative lcsc groups. We introduce the notion of Gelfand pairs which are a powerful tool to develop a spherical Fourier theory on the spaces we have in mind. The corresponding abstract Fourier transform allows us to define the spherical diffraction measure for non-commutative quasicrystals. Generalizing the classical (abelian) case, we explain why regular cut-and-project sets arising from cocompact lattices amount to pure point diffraction. Joint work with Michael Björklund and Tobias Hartnick. | ||

| Beyond the Standard Model (of High-Intensity Laser Particle Interactions) Prof. Thomas Heinzl (Plymouth University) The interaction of matter with high-intensity lasers is traditionally described by modelling the laser as a plane wave background field. This description becomes invalid (i) at ultra-high intensities requiring strong focussing and (ii) whenever there is substantial back-reaction on the external field yielding e.g. beam depletion. I will describe a number of theoretical attempts aimed at improving the current methodology to deal with these rather extreme, but soon experimentally feasible, conditions. | ||

| Non-commutative quasicrystals I Felix Pogorzelski, Technion Haifa, Israel Abstract: The investigation of aperiodic point sets originates back to work of Meyer in the 70ies who pursued harmonic analysis on harmonious sets in Euclidean space. Shechtman's discovery of physical quasicrystals (1982) via laser experiments diffraction) triggered a boom of the mathematical analysis of the arising scatter patterns. In recent work with Michael Björklund and Tobias Hartnick, we developed a spherical diffraction theory for cut-and-project sets in general lcsc groups, thus advancing into the non-commutative world. This seminar aims at describing these non-commutative quasicrystals, as well as the dynamical systems which naturally arise from them. We explain further how to use these tools in order to derive the existence and the approximation of the autocorrelation measure. | ||

| The cross-correlation search for stochastic and continuous gravitational wave sources Prof. Sanjeev Dhurandhar Abstract- The cross-correlation search can be used to map the stochastic gravitational wave (GW) background, as well as track continuous wave sources such as spinning neutron stars. An astrophysical GW background will likely arise from an incoherent superposition of unmodelled and/or unresolved sources and cosmological GWbackgrounds (CGWB) are also predicted in certain scenarios. The basic statistic used is the cross-correlation between the data from a pair of detectors. In order to ‘point’ the pair of detectors at different locations one must suitably delay the signal by the amount it takes for the GW to travel to both detectors corresponding to a source direction. Then the raw sky map of the GW background is the signal convolved with a beam response function that varies with location in the sky. The true sky map is obtained by numerically deconvolving the beam function in the integral (convolution) equation by using the maximum likelihood approach. We apply these methods to the Virgo cluster which could be "hot spot" of stochastic GW originating from rotating neutron stars which is a suitable source for this method. We then show how this method can be adapted to observe continuous wave sources such as spinning neutron stars. This method can be used as a trade-off between computational cost and sensitivity. This method can also be employed for LMXB searches such as Sco X-1. Work on how to speed up the searches is in progress. | ||

| Dual Foliation Formulations of General Relativity or "how I learned to stop worrying and love coordinates" by Dr. David Hilditch, TPI Jena Abstract: When solving general relativity numerically for a given physical problem we must use a formulation of the field equations for which the resulting partial differential equation problem is well-posed. Building such a good formulation usually requires making a coordinate choice. This leads to the standard statement that `gauge freedom in general relativity is the choice of coordinates'. The latter two facts have long bothered me, because one of the first lessons in relativity is that coordinates should in some sense not matter. In my talk I will explain the solution to my earlier confusion. Time permitting I will also describe ongoing work to exploit the solution for practical calculations. | ||

| Constraints as evolutionary systems Prof. Racz Abstract: In this talk the constraint equations for smooth spaces satisfying Einstein's equations will be considered. It is shown that, regardless whether the primary space is Riemannian or Lorentzian, the constraints can always be put into the form of an evolutionary system comprised either by a first order symmetric hyperbolic system and a parabolic equation or, alternatively, by a strongly hyperbolic system subsided by an algebraic relation. The (local) existence and uniqueness of solutions to these evolutionary systems is also shown verifying thereby that the proposed evolutionary approach provides a viable alternative to the apparently unique conformal method. | ||

| Surrogate models of gravitational waveforms from numerical relativity simulations of binary black hole mergers Jonathan Blackman, Caltech Abstract: GW150914 was the first detection of gravitational waves from a binary black hole merger, bringing us into the era of gravitational wave astronomy. From such gravitational wave detections, we can put constraints on deviations from general relativity (GR), as well as measure the masses and spins of the black holes involved in the merger. Such measurements require knowledge of the gravitational waveforms predicted by GR for all relevant masses and spins. Numerical relativity (NR) simulations are now sufficiently robust that we can accurately simulate binary black hole mergers and obtain the waveform for all but the most extreme parameters, but they are too computationally expensive for a dense coverage of the parameter space. The effective-one-body model and phenomenological waveform models agree well with NR for the parameters of GW150914, but could be insufficiently accurate for estimating the parameters of a loud gravitational wave detection in other regions of the parameter space. NR surrogate models attempt to rapidly and accurately interpolate the waveforms from a set of NR simulations over a subset of parameter space. Using the Spectral Einstein Code (SpEC), we have built NR surrogate models for non-spinning binaries with mass ratios up to 10, and for spinning precessing binaries with a restricted spin direction on the smaller black hole. They typically perform an order of magnitude better than other waveform models when compared to NR waveforms which were not included in the surrogate training set, and can be used in gravitational wave parameter estimation. | ||

| Causal Space-time on a Null Lattice Prof. Dr. Martin Schaden, Rutgers University Abstract: I propose a discrete model of Quantum Gravity based on the same principle as the Global Positioning System: the intersection of forward light-cones from four spatially separate events (with some restrictions) determines another event. I show that a causal manifold can thus be described by a topologically hypercubic lattice with light-like links; the length of the spatial diagonal of each plaquette being determined by spinors describing the light-like edges. This lattice model has an SL(2,C) x U^4(1) structure group and is geometric. The description foliates in a causal and physically transparent manner. The observables, the most general local action and the integration measure of this model are all determined by this stucture group and for smooth configurations have well-known continuum limits. Consistency constraints on a configuration to describe a causal manifold are derived and a one-parameter ambiguity of the invariant integration measure is exploited to regularize the model. Finally the SL(2,C) structure group is uniquely localized and the integration measure expressed in terms of geometric invariants. Should time and interest permit, I will also discuss global issues and show numerical results on a small lattice describing the vicinity of the Big Bang in the (unphysical) limit where the cosmological term dominates the dynamics. | ||

| Spontaneous breaking of Lorentz symmetry in QED3 Dr. Lukas Janssen (TU Dresden) Abstract: The phase diagram of quantum electrodynamics in three space-time dimensions as a function of fermion flavor number N exhibits two well-known phases: at large N > Nc1 the system is in a conformal gapless state, while for small N < Nc2 the fermions are expected to develop a dynamical mass due to spontaneous chiral symmetry breaking. Using epsilon expansion near the lower critical dimension of two, in combination with the recent results on the generalization of the F theorem to continuous dimension, we show that Nc1 > Nc2. There is therefore an intermediate range of values of N at which a third phase is stabilized. We demonstrate that this phase is characterized by spontaneous breaking of Lorentz symmetry, in which a composite vector boson field acquires a vacuum expectation value with the fermions and the photon remaining massless. | ||

| Nonequilibrium entropy production for open quantum systems Prof. Eric Lutz (FAU Erlangen) Abstrakt: Entropy production is a fundamental quantity of nonequilibrium thermodynamics. We here discuss exact microscopic expressions for the nonequilibrium entropy production of closed and open quantum systems that are driven arbitrarily far from equilibrium, in particular beyond the linear response regime. We additionally consider the entropy production rate, which provides information about the speed of nonequilibrium processes, and show that they are bounded from above for quantum systems. The connection with the notion of quantum speed limit is addressed. | ||

| Magnetic Vortices, vortex lattices and automorphic functions Prof. Dr. Israel Michael Sigal, Univ. Toronto Abstract: I will review recent results concerning the Ginzburg - Landau equations. These equations were first developed to understand macroscopic behaviour of superconductors; later, together with their non-Abelian generalizations - the Yang-Mills-Higgs equations, they became a key part of the standard model in elementary particle physics. They also have found important applications in geometry and topology. The Ginzburg - Landau equations have remarkable solutions, localized topological solitons, called the magnetic vortices in the superconductivity and the Nielsen-Olesen or Nambu strings in the particle physics, as well as extended ones, magnetic vortex lattices. I will review the existence and stability theory of the vortex lattice solutions and how they relate to the modified theta functions appearing in number theory and algebraic geometry. Certain automorphic functions play a key role in the theory described in the talk. | ||

| Critical scaling in the Large-N O(N) model and its possible connection to quantum gravity Dr. Péter Mati (Budapest/Szeged) The critical scaling of the large-N O(N) model in higher dimensions using the exact renormalization group equations will be discussed. Particular attention is paid to the case of d=5 where the scaling exponent of the correlation length has the value 1/3, which coincides with the scaling exponent of quantum gravity in one fewer dimensions. Convincing results show that this relation could be generalized to arbitrary number of dimensions above five. Some aspects of AdS/CFT correspondence will be also discussed. | ||

| QED in the infrared Dr. Péter Mati (Budapest/Szeged) Joint Seminar with Helmholtz Institute Jena Infrared (IR) singularities in massless gauge theories are known since the foundation of quantum field theories. The root of this problem can be tracked back to the very definition of these long-range interacting theories such as QED. The IR catastrophe and its resolution by cancelling the divergences will be discussed. The Bloch-Nordsieck model provides the deep IR description of QED, and in its framework all the radiative corrections to the electron propagator can be fully summed, giving the infra-particle interpretation to the electron. This solution can be obtained by using the functional technique based on the Schwinger-Dyson equation with the aid of the Ward-Takahashi identities. At finite temperatures we use the Keldysh description, that will give a matrix structure to the equation. Again an analytic solution can be obtained for the exact spectral function. The finite temperature solution provides a natural explanation of IR finiteness. | ||

Quite interestingly, it has been discovered that the supercritical Brill waves, a commonly used family of initial data, cannot be successfully evolved with the moving puncture gauge, popular for black hole simulations. In this talk, we present our work in progress on using a modification of the moving puncture gauge to evolve such data. | ||

The analysis presented covers the subextremal, extremal and hyperextremal cases. The implications of this analysis for the study of nonlinear perturbations of members of the Schwarzschild-de Sitter family of spacetimes are discussed. | ||

| Towards quasicrystals in non-commutative spaces Felix Pogorzelski Abstract: In 2011, Dan Shechtman was awarded the Nobel prize in chemistry for his discovery of physical quasicrystals. Via diffraction experiments, he observed in 1982 that for some materials, there are interference patterns whose symmetries are not compatible with crystallographic structures in three-dimensional space. This triggered the mathematical examination of those structures as Dirac combs over uniformly discrete point sets in Euclidean space. In the past decades, mathematical diffraction theory evolved into a beautiful and rich research topic combining various disciplines such as functional analysis, fourier analysis and dynamical systems. One method to obtain a large class of interesting quasicrystals is via so-called cut-and-project schemes, introduced by Meyer in the 70s. This talk presents the basics of diffraction for cut-and-project schemes over locally compact abelian groups and describes how the theory can be extended to the non-commutative case. This is joint work with Michael Björklund (Chalmers Göteborg) and Tobias Hartnick (Technion Haifa). | ||

| Entanglement entropy in a holographic model of the Kondo effect Mario Flory MPI Munich Starting from a holographic model a magnetic impurity interacting with a strongly coupled system, I focus on the challenges of computing gravitational backreaction in this model, which demands a study of the Israel junction conditions. I present general results on these junction conditions which may be relevant more generally in the AdS/boundary CFT correspondence. Furthermore, similar junction conditions for a bulk Chern-Simons field appearing in the holographic Kondo model are discussed. I then focus on the computation and interpretation of entanglement entropy in the holographic Kondo model. The holographic g-theorem will be discussed as well as a geometric construction that allows to reproduce results obtained by conformal perturbation theory on the boundary. | ||

| Invariant classification and limits of superintegrable systems Dr. Jonathan Kress, University of New South Wales (Sydney) Abstract: A classical Hamiltonian system possessing more globally defined conserved quantities than degrees of freedom is said to be superintegrable. Such systems possessing the maximum number of conserved quantities quadratic in the momenta have been much studied because of their connection with separation of variables and special functions. In two dimensions it has been shown that singular limits between `non-degenerate' superintegrable systems mirror limits between othogonal polynomials in the Askey scheme. As a first step in extending this to higher dimensions, all second order superintegrable systems with a `non-degenerate' potential have recently been classified and shown to arise by singular limits from a generic system on the 3-sphere. This classification and the relationships between the systems, which is joint work with Joshua Capel and Sarah Post, will be discussed. | ||

| Exploring some elliptic operators in Gravitation and Physical Oceanography Dr. Jose Luis Jaramillo, Universität Brest Abstract: We discuss two physical problems in which the study of the spectral properties of certain elliptic operators, related to the Laplace-Beltrami operator on compact Riemannian manifolds, appear naturally. The first problem dwells in a gravitational context, namely the stability of black hole apparent horizons, and addresses the properties of a non-selfadjoint elliptic operator defined on closed codimension-2 surfaces. The second problem deals with the slow motions in the ocean and brings about the discussion of the Laplace-Beltrami operator associated with an effective metric in the oceanic basic, namely a compact manifold with boundaries. The two problems are technically and conceptually related, in particular through the spectral approach we adopt for their study. The main goal in this talk is to present a brainstorm exercise aiming at identifying the most suited mathematical strategy for these problems. | ||

| How much nonperturbative is the nonperturbative regime of QCD? Dr. Matthieu Tissier, LPTMC (Laboratoire de Physique Théorique de la Matière Condensée), Université Pierre et Marie Curie, Paris. ABSTRACT Studying the high energy regime of QCD is a problem that can be tackled by perturbation theory. This is a consequence of asymptotic freedom, which states that the coupling constant of QCD decreases when increasing the energy. The low energy regime (often called the "nonperturbative regime") is much more difficult to access, mainly because the standard perturbation theory is not applicable anymore. Nonetheless, I will discuss the possibility of studying the low-energy regime of QCD perturbatively. The main idea is to perform perturbation theory not around the usual Faddeev-Popov action, but around a simple extension of the latter, known as the Curci-Ferrari model. I will discuss the properties of this model and present several 1-loop calculations 1) for correlation functions 2) for the phase diagram of QCD. Comparison with lattice data show that all these quantities can be reproduced with a precision of the order of 15-20%. | ||

| On the Search for Inhomogeneous Phases in Fermionic Models Dr. Felix Karbstein Helmholtz-Institut Jena We revisit the Gross-Neveu model with N fermion flavors in 1+1 dimensions and compute its phase diagram at finite temperature and chemical potential in the large-N limit. To this end, we double the number of fermion degrees of freedom in a specific way which allows us to detect inhomogeneous phases in an efficient manner. We show analytically that this "fermion doubling trick" predicts correctly the position of the boundary between the chirally symmetric phase and the phase with broken chiral symmetry. Most importantly, we find that the emergence of an inhomogeneous ground state is predicted correctly. We critically analyze our approach based on this trick and discuss its applicability to other theories, such as fermionic models in higher dimensions, where it may be used to guide the search for inhomogeneous phases. | ||

| The Topology of Chiral Vector Bundles (topological insulators of type AIII) Dr. Giuseppe de Nittis, Friedrich-Alexander-Universität Erlangen-Nürnberg The classification of topological states of matter is an important hot topic in mathematical physics. In this talk I will describe a new approach to the classification of topological quantum systems in class AIII which is based on the study of a new category of vector bundles. The objects of this category, the chiral vector bundles, are pairs constituted by a complex vector bundle along with one of its automorphisms. We provide a classification for the homotopy equivalence classes of these objects which is based on the construction of a suitable classifying space. The computation of the cohomology of the latter allows us to introduce a proper set of characteristic cohomology classes: Some of those just reproduce the ordinary Chern classes but there are also new odd-dimensional classes which take care of the extra topological information introduced by the chiral structure. Chiral vector bundles provide the proper geometric model for topological quantum systems in class AIII, namely for systems endowed with a (pseudo-)symmetry of chiral type. The classification of the chiral vector bundles over sphere and tori (explicitly computable up to dimension 4) recover the commonly accepted classification for topological insulators of class AIII which is usually based on the K-group K1. However, this new classification turns out to be even richer since it takes care also for the possibility of non trivial Chern classes. | ||

Our approach is to directly solve the fundamental embedding equation supplemented by six conditions that fix translations and rotations of the embedded surface. This set of equations is discretized by means of a pseudospectral collocation point method. The resulting nonlinear system of equations are then solved by a Newton-Raphson scheme. We explain our numerical algorithm in detail. By studying several examples we show that our method converges provided we start the Newton-Raphson scheme from a suitable initial guess. Our novel method is very efficient for smooth 2-metrics. | ||

| Lightlike inhomogenities in worldline pair creation Dr. Anton Ilderton, Chalmers University Göteborg The locally constant field approximation (LFCA) is commonly used to calculate the nonperturbative pair production probability in electromagnetic fields. In certain classes of fields, for example longitudinal electric fields depending on lightfront time, the LCFA is known to be exact. Using the worldline description of the effective action, we show that the reason for this is closely tied to the zero-mode problem of lightfront quantisation, and the so-called “triviality” of the lightfront vacuum. | ||

| Spectral theory for continuum one-dimensional quasicrystal models Dr. Christian Seifert, Technische Universität Hamburg-Harburg We consider an ergodic family $(H_\omega)_{\omega\in\Omega}$ of continuum one-dimensional Schr\"odinger operators, where we allow for measures as potentials. We show that the random operator $H$ has Cantor type spectra of Lebesuge measure zero under suitable finite local complexity conditions on the potentials. Such operator families appear in the study of quasicrystalline models. | ||

| Binary neutron stars: what we understand and what we don't From Luciano Rezzolla for the GWA14 conference I will review the recent progress made in modelling binaries of compact stars and the role played by magnetic fields and the equation of state in their evolution. Special attention will be paid to highlighting how the progress of ab-initio fully relativitistic calculations can be used to explain several aspects of the phenomenology of short gamma-ray burst, but also how new observations on the X-ray afterglows represent new riddles for the theoretical modeling. | ||

| Constraining the nature of gravitational waves with binary pulsar experiments From Paulo Freire for the GWA14 conference In this talk I present some recent pulsar timing experiments for double neutron stars that test general relativity's quadrupolar gravitational wave emission formula with unprecedented precision. I then present the results of timing of millisecond pulsar - white dwarf systems that severely constrain the emission of dipolar gravitational waves (DGW) for a wide range of neutron star masses. Apart from constraining (and in some cases excluding) alternative theories of gravity that predict DGW emission, these results reinforce our confidence in the templates being used to search for the GW signal of NS-NS and NS-BH inspiral events in the advanced LIGO and Virgo detectors. | ||

| Highest order post-Newtonian dynamics of non-spinning and spinning compact binaries in general relativity From Gerhard Schäfer for the GWA14 conference The talk delivers insight into the calculations of highest order post-Newtonian (PN) Hamiltonians for binary black holes. The conservative dynamics is presented up to 4 PN order for binaries with both non-spinning and spinning components, where the spins are counted of 0.5 PN order. The related dissipative radiation reaction dynamics is known up to 4.5 PN order. As application, the Innermost Stable Circular Orbit for spinless binaries is given through 4 PN order and the test-body limit is compared with the exactly known ISCO of a test-body orbiting a Schwarzschild black hole. | ||

I will give an update on numerical results with SpEC, and will discuss several applications of the simulations, among them the construction of waveform models within the effective-one-body formalism, the study of gravitational self-force effects through comparable-mass binary black hole simulations, and a comparison of the post-Newtonian precession dynamics with numerical simulations. | ||

| Post-merger Oscillations in Binary Neutron Star Mergers from Nikolaos Stergioulas for the GWA14 conference Because of the recent discovery of two-solar-mass neutron stars, the equation of state of high density matter is likely to be sufficiently stiff to allow for a long-lived remnant, when two neutron stars merge. The merger excites a number of oscillation modes, having large (nonlinear) amplitude, that are interesting as gravitational waves sources for second- and third-generation interferometric detectors. Apart from a dominant linear oscillation mode, additional nonlinear contributions appear. I discuss the main properties of these oscillations as well as the prospects of constraining the mass and radius (and thus the equation of state) with future detections. | ||

| Gravitational wave detection using squeezed light from Roman Schnabel for the GWA14 Conference Current gravitational wave (GW) detectors are Michelson-type kilometre-scale laser interferometers measuring the distance changes between in vacuum suspended mirrors. The sensitivity of these detectors is limited by quantum noise of the laser light. Since 2010, GEO600 has been using so-called nonclassical light that has a ‘squeezed’ quantum noise, and it has been demonstrated that squeezed light is able to increase the GW detector sensitivity at shot-noise limited frequencies. In future, squeezed light might be used to further improve the sensitivity of GW detectors, then also at radiation pressure noise dominated frequencies and at frequencies where photon-phonon scattering is limiting the detectors performance. | ||

| Gravitationswellenastronomie: Bald Neues von der dunklen Seite des Universums! Public Talk of the GWA14 Conference from Karsten Danzmann Können wir das Universum hören? Auf den ersten Blick ist das eine unsinnige Frage, denn natürlich gibt es im Weltall keine Luft, in der sich der Schall ausbreiten könnte. Wenn aber unsere Ohren nur empfindlich genug wären, dann könnten sie auf eine besondere Art von Wellen reagieren: auf Gravitationswellen! Vor mehr als 90 Jahren sagte Albert Einstein die Existenz von Gravitationswellen als Konsequenz seiner allgemeinen Relativitätstheorie voraus. Gravitationswellen sind winzige Verbiegungen des Raumes und der Zeit, die von schnellbewegten, großen Massen erzeugt werden und sich mit Lichtgeschwindigkeit wellenförmig ausbreiten. Sie wurden noch nie direkt nachgewiesen. Mehrere laserinterferometrische Gravitationswellendetektoren mit Armlängen von Kilometern werden gegenwärtig auf der Erde betrieben, um Gravitationswellen zu erforschen, darunter auch GEO600 in der Nähe von Hannover. Bald folgen Detektoren im Weltraum mit Millionen km Armlänge, insbesondere die Satelliten-Mission LISA. Ausgangspunkt für diese geheimnisvollen Wellen könnten z. B. verschmelzende Doppelsterne, Neutronensterne, Supernovae, Schwarze Löcher und der Urknall sein. Ihre Beobachtung erfordert modernste Lasertechnologie und Messungen an der quantenmechanischen Nachweisgrenze. | ||

| Beyond the second generation of gravitational wave detectors from Ronny Nawrodt for the GWA14 Conference Gravitational wave detectors are currently upgraded to the 2nd generation achieving extremely high sensitivities in a wide frequency band. A first direct detection of gravitational waves is expected once these instruments are getting online. Such a detection will mark the starting point for a gravitational wave based astronomy. Thus, detectors of the third generation are designed to be used as efficient astronomical observatories. For this purpose the sensitivity of the 2nd generation detectors has to be enhanced. As the sensitivity of current instruments approaches the thermal noise floor of their fused silica components a radical change of materials is necessary. Additionally, 3rd generation detectors will be operated at cryogenic temperatures to further reduce thermal noise and increase their sensitivity. This talk will give an overview of proposed technologies towards 3rd generation detectors leading to a 10 times higher sensitivity throughout the audio band. The focus will lie on the selection of materials for the optics as well as the suspension elements according to their properties. The characterisation of these materials and the choice of their operational temperature is discussed as well. | ||

| Simulating full QCD at nonzero density using the complex Langevin equation (Denes Sexty, University of Heidelberg) Abstract: The complex Langevin method is extended to full QCD at non-zero chemical potential. The use of gauge cooling stabilizes the simulations at small enough lattice spacings. At large fermion mass the results are compared to the HQCD approach, in which the spatial hoppings of fermionic variables are neglected, and good agreement is found. The method allows simulations also at high densities, all the way up to saturation. Preliminary results of a comparison to the reweighting approach are presented. | ||

| Excited states and hadron resonances from Lattice QCD Daniel Mohler (Fermilab, USA) Abstract: A selective review of recent progress in lattice QCD calculations of excited states and QCD resonances is presented. The challenges of extracting excited state energy levels and of their interpretation will be discussed, using data from recent simulations as examples. Emphasis will be placed on simulations that explicitly include multi-particle (meson-meson and meson-baryon) states in channels with either a low-lying QCD resonance or with a bound state close to threshold. | ||

| The discovery of a Higgs Boson at CERN - opening the door to a new world Prof. Kobel (Uni Dresden) Abstract: A thorough study of the properties of the new particle, found by the ATLAS and CMS experiments at 126 GeV in 2012 has meanwhile revealed: We indeed have found a Higgs Boson. According to the Standard Model it would be the first member of a so far unseen class of particles: a fundamental scalar, i.e. a Spin 0 state, not composed of any further constituents. If remains to be proven, if this is the really the case, and if there might be even more such Higgs particles, as predicted in many extensions of the Standard Model like Supersymmetry. But even within the Standard Model several vertices related to the Higgs Bosons remain to be observed. One is part of the scattering of two Vector Bosons VV->VV, where V=W,Z. For not violating basics rules of probability ("unitarity") this scattering requires in the Standard Model the regulating contribution of Higgs-Boson exchange. This so far unobserved scattering process thus constitutes a crucial test of the properties of the 126 GeV Higgs Boson, and of the mechanism of electroweak symmetry breaking. | ||
