Universality of the second mixed moment of the characteristic polynomials of the 1D Gaussian band matrices
Update: 2012-09-24
Description
We consider the asymptotic behavior of the second mixed moment of the characteristic polynomials of the 1D Gaussian band matrices, i.e. of the hermitian matrices Hn with independent Gaussian entries such that ⟨HijHlk⟩=δikδjlJij, where J=(−W2△+1)−1. Assuming that W2=n1+θ, 0<θ<1, we show that this asymptotic behavior (as n→∞) in the bulk of the spectrum coincides with those for the Gaussian Unitary Ensemble.
