Flux representation of an effective Polyakov loop model for QCD thermodynamics (1104.2503v2)
Published 13 Apr 2011 in hep-lat, cond-mat.stat-mech, hep-ph, and hep-th
Abstract: We discuss an effective Polyakov loop model for QCD thermodynamics with a chemical potential. Using high temperature expansion techniques the partition sum is mapped exactly onto the partition sum of a flux model. In the flux representation the complex action problem is resolved and a simulation with worm-type algorithms becomes possible also at finite chemical potential.
