Eigenvalue statistics of the real Ginibre ensemble

Statistical Mechanics 2015-06-16 v1

Abstract

The real Ginibre ensemble consists of random N×NN \times N matrices formed from i.i.d. standard Gaussian entries. By using the method of skew orthogonal polynomials, the general nn-point correlations for the real eigenvalues, and for the complex eigenvalues, are given as n×nn \times n Pfaffians with explicit entries. A computationally tractable formula for the cumulative probability density of the largest real eigenvalue is presented. This is relevant to May's stability analysis of biological webs.
