Chiral Disorder and QCD Phase Transitions

Abstract

If QCD is to undergo a second order phase transition, the light quark return probability is universal for large times at the critical point. We show that this behavior is distinct from the one expected at the mobility edge of a metal-insulator transition or a percolation transition in d$\le 4$. Our results are accessible to current lattice QCD simulations.
