Breakdown of Universality in Random Matrix Models
Satoshi Iso, Andrew Kavalov
Abstract
We calculate smoothed correlators for a large random matrix model with a potential containing products of two traces W1(M) · W2(M) in addition to a single trace V(M). Connected correlation function of density eigenvalues receives corrections besides the universal part derived by Brezin and Zee and it is no longer universal in a strong sense.
