Lattice Simulations of QCD-like Theories at Finite Density — •Philipp Scior1, Lorenz von Smekal2, and Björn Wellegehausen2 — 1Institut für Theoretische Physik, Westfälische Wilhelms-Universität Münster — 2Institut für Theoretische Physik, Justus-Liebig-Universität Gießen
We study QCD-like theories at finite density. In particular we investigate the cold and dense regime of the phase diagram where we expect to find the Silverblaze property realized as Bose-Einstein-condensation of diquarks or a first order liquid-gas transition depending on the gauge group of the theory. Part of our results are derived in the limit of heavy quark masses by using a three-dimensional Polyakov loop theory. This theory can be derived from the full QCD-like theory by a combined strong coupling and hopping expansion.
