✦ Synopsis
We investigate the eigenvalue spectrum of the staggered Dirac matrix in two color QCD at nite chemical potential. The pro les of complex eigenvalues close to the origin are compared to a complex generalization of the chiral Gaussian Symplectic Ensemble, con rming its predictions for weak and strong non-Hermiticity. They di er from the QCD symmetry class with three colors by a level repulsion from both the real and imaginary axis.
