The spectrum of the Dirac-Wilson operator in Nf=1 QCD — •Jair Wuilloud — Institut für theoretische Physik (WWU); Wilhelm-Klemm Str., 9; 48149 Münster
For QCD with Nf=1 flavour, lattice numerical studies of the phase structure should allow for the investigation of questions like the definition of the quark mass and a possible symmetry breaking of CP.
Around interesting points in the phase diagram, situations arise where the determinant of the Dirac-Wilson operator becomes negative and its sign has to be computed.
We discuss techniques for evaluating the spectrum of the Dirac-Wilson operator and the sign of its determinant.
