Simulation of Lattice Gauge Theories

The simulation of lattice gauge theories is a major research activity of the department of physics at the university of Bielefeld since the beginning of the '80s. The main interest has been in the simulation of finite temperature field theories, in particular the study of the phase transition to the Quark-Gluon-Plasma.
In the following we specify some of our research activities and give links to recent publications.
