On the moments of characteristic polynomials

Mathematical Physics 2025-04-18 v1 math.MP

Abstract

We examine the asymptotics of the moments of characteristic polynomials of N×NN\times N matrices drawn from the Hermitian ensembles of Random Matrix Theory, in the limit as NN\to\infty. We focus in particular on the Gaussian Unitary Ensemble, but discuss other Hermitian ensembles as well. We employ a novel approach to calculate asymptotic formulae for the moments, enabling us to uncover subtle structure not apparent in previous approaches.
