Abstract

We compare the low eigenvalue spectra of the Overlap Dirac operator on two sets of configurations at μ_I/μ_I^c = 0.5 and 1.5 generated with dynamical staggered fermions at these isospin chemical potential on 24³ × 6 lattices. We find very small changes in the number of zero modes and low lying modes which is in stark contrast with those across the corresponding finite temperature phases where one sees a drop across the phase transition. Possible consequences are discussed.
