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 $β=4.6$.
