Query: Equivalence of Matrix Models for Complex QCD Dirac Spectra   Two different matrix models for QCD with a non-vanishing quark chemical
potential are shown to be equivalent by mapping the corresponding partition
functions. The equivalence holds in the phase with broken chiral symmetry. It
is exact in the limit of weak non-Hermiticity, where the chemical potential
squared is rescaled with the volume. At strong non-Hermiticity it holds only
for small chemical potential. The first model proposed by Stephanov is directly
related to QCD and allows to analyze the QCD phase diagram. In the second model
suggested by the author all microscopic spectral correlation functions of
complex Dirac operators can be calculated in the broken phase. We briefly
compare those predictions to complex Dirac eigenvalues from quenched QCD
lattice simulations.
