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.

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.

Ernst Mach and Machian effects in general relativity
Prof. Jiri Bicak, Charles University (Prague)

Abstract: I shall start with some remarks on Ernst Mach (+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.

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.

Numbers and functions in quantum field theory
Dr. Oliver Schnetz, Univ. Erlangen

Quantum field theories describe the fundamental interactions between physical particles. 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


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


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


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

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

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)


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

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.

Collapse of the Brill waves in a moving-puncture-like gauge (WIP)
Anton Khirnov


One of the open problems in numerical relativity is that of the critical collapse of gravitational waves into a black hole. 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.

Conformal properties of the Schwarzschild-de Sitter spacetime
Dr. Juan Valiente-Kroon, School of Mathematical Sciences at Queen Mary, University of London

In this talk I will show how the asymptotic initial value problem for the conformal Einstein field equations, whereby one prescribes initial data on a spacelike hypersurface representing the conformal boundary, can be used to study various conformal aspects of the Schwarzschild-de Sitter spacetime. 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


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.

Abstract: I will review a new approach to constructing interacting (Euclidean) QFTs in 4 dimensions via the operator product expansion (OPE), and a number of important results that have been proven in the last years using the Polchinski-Kopper flow equation framework, such as existence, convergence and factorisation properties of the OPE in a perturbative sense for non-gauge theories. Lastly, I present on-going work on the generalisation to gauge theories.

Invariant classification and limits of superintegrable systems
Dr. Jonathan Kress, University of New South Wales (Sydney)

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.

Gauge Theory of the (infinite-dimensional) Translation Group and Gravitation
Dr. Christian Wiesendanger, Zurich
Short Abstract: The seminar will address two interrelated questions:
- What if inertial and gravitational masses would differ off the mass shell? Could this be the basis of a theory of gravitation?
- Can gauge theories of infinite-dimensional gauge groups (example is the 4-dim Translation Group) be mathematically consistently defined so that the classical gauge field Hamiltonian is positive-definite and the quantum theory renormalizable?

Finite differencing schemes for GLM-RMHD (Master Thesis Defense)
by Tom Dörffel
A class of finite differencing high-resolution shock-capturing methods for special relativistic magnetohydrodynamics is presented. The divergence condition is controlled by the divergence cleaning approach of Dedner (2002). By performing a series of standard tests the schemes are proven to be high-order accurate for smooth solution and stable in the case of strong shocks.

Exploring some elliptic operators in Gravitation and Physical Oceanography
Dr. Jose Luis Jaramillo, Universität Brest

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.


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.

New efficient algorithm for the isometric embedding of 2-surface metrics in 3 dimensional Euclidean space
Wolfgang Tichy, Florida Atlantic University

We present a new numerical method for the isometric embedding of 2-geometries specified by their 2-metrics in three dimensional Euclidean space. 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.

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

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.

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)


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)

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)


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
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.

Workshop: Numerical and Mathematical Relativity
The aim of the workshop is to give numerical relativists the opportunity to learn about topics in mathematical relativity beyond the level that they would typically be discussed by the numerical relativity community, and to inform the mathematical community about the current state of the art in numerical simulations. To this end talks will be presented over the following topics:

  • Global results for numerical relativists.
  • Formulations of general relativity.
  • Boundary conditions and well-posedness of the initial boundary value problem.
  • Accurate and stable discretizations of spacetime.

Please contact us for further details.
