Lecture: Computational Methods for Particle Physics (WS 2018/19)

Dates

First course: 14.-16.11.2018

Second course: 15.-18.1.2019

Abstract

Programming course and exercises.

Preliminary outline

First part

  • Ising model simulations.
  • Ising model and related theories, low and high temperature expansions, simulation algorithms

Second part

  • Gauge principle and gauge theories in the continuum, formulation of pure gauge theory on the lattice.
  • Simulation algorithm for SU(2) pure gauge theory, implementation of SU(2) metropolis algorithm

Material (outdated: Solutions removed/in new course)

Lecture / Exercises 1

Lecture / Exercises 2

This exercise is to write a simple metropolis update code for SU(2) pure gauge theory. In order to simplify the task, several routines for handling configurations, links, matrices, and random numbers are already provided.
C++ and Fortran code as a staring point for the exercise of SU(2) pure gauge lattice simulations.
For the C++ program you have to call "make Eigen" first.
