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 and β = 4.3, but not at β = 4.6 and β = 5.0. At non-zero temperature the Aoki phase was found to exist also at β = 4.6.
