Abstract / Bemerkung
We compare analytic predictions of non-Hermitian chiral random matrix theorywith the complex Dirac operator eigenvalue spectrum of two-colour lattice gaugetheory with dynamical fermions at nonzero chemical potential. The Diraceigenvalues come in complex conjugate pairs, making the action of this theoryreal, and positive for our choice of two staggered flavours. This enables us touse standard Monte-Carlo in testing the influence of chemical potential andquark mass on complex eigenvalues close to the origin. We find an excellentagreement between the analytic predictions and our data for two differentvolumes over a range of chemical potentials below the chiral phase transition.In particular we detect the effect of unquenching when going to very smallquark masses.
