2 Oct 1995 | | Subject: | cond-mat | | Abstract: | Unitary ensembles of large N x N random matrices with a non-Gaussian probability distribution P[H] ~ exp{-TrV[H]} are studied using a theory of polynomials orthogonal with respect to exponential weights. Asymptotically exact expressions for density of levels, one- and two-point Green’s functions are calculated. We show that in the large-N limit the properly rescaled local eigenvalue correlations are independent of P[H] while global smoothed connected correlations depend on P[H] only through the endpoints of spectrum. We also establish previously unknown intimate connection between structure of Szegö function entering strong polynomial asymptotics and mean-field equation by Dyson. | | Source: | arXiv, cond-mat/9510002 | | Services: | Forum | Review | PDF | Favorites | |
