Abstract

We consider N×NN\times N random matrices of the form H=W+VH=W+V where WW is a real symmetric or complex Hermitian Wigner matrix and VV is a random or deterministic, real, diagonal matrix whose entries are independent of WW. We assume subexponential decay for the matrix entries of WW, and we choose VV so that the eigenvalues of WW and VV are typically of the same order. For a large class of diagonal matrices VV, we show that the local statistics in the bulk of the spectrum are universal in the limit of large NN.
