The Aoki phase for N_f=2 Wilson fermions revisited

High Energy Physics - Lattice 2009-09-29 v1

Abstract

We report on a numerical reinvestigation of the Aoki phase in full lattice QCD with two flavors of unimproved Wilson fermions. For zero temperature the Aoki phase can be confirmed at inverse coupling β=4.0\beta=4.0 and β=4.3\beta=4.3, but not at β=4.6\beta=4.6 and β=5.0\beta=5.0. At non-zero temperature the Aoki phase was found to exist also at β=4.6\beta=4.6.
