We consider the asymptotic behavior of the second mixed moment of the characteristic polynomials of 1D Gaussian band matrices, i.e., of the Hermitian N × N matrices HN with independent Gaussian entries such that 〈HijHlk〉 = δikδjlJij, where $${J=(-W^2 riangle+1)^{-1}}$$J=(-W2▵+1)-1. Assuming that $${W^2=N^{1+ heta}}$$W2=N1+θ, $${0 < heta leq 1}$$0<θ≤1, we show that the moment’s asymptotic behavior (as $${N oinfty}$$N→∞) in the bulk of the spectrum coincides with that for the Gaussian Unitary Ensemble.
