Bulk universality for deformed Wigner matrices

We consider random matrices of the form where is a real symmetric or complex Hermitian Wigner matrix and is a random or deterministic, real, diagonal matrix whose entries are independent of . We assume subexponential decay for the matrix entries of , and we choose so that the eigenvalues of and are typically of the same order. For a large class of diagonal matrices , we show that the local statistics in the bulk of the spectrum are universal in the limit of large .
