Macroscopic Universality: Why QCD in Matter is Subtle

We use a chiral random matrix model with ${2N}_f$ flavors to mock up the QCD Dirac spectrum at finite chemical potential. We show that the $1/N$ approximation breaks down in the quenched state with spontaneously broken chiral symmetry. The breakdown condition is set by the divergence of a two-point function that is shown to follow the general lore of macroscopic universality. In this state, the fermionic fluctuations are not suppressed in the large $N$ limit.
