Gaussian beta ensembles at high temperature: eigenvalue fluctuations and bulk statistics

Abstract

We study the limiting behavior of Gaussian beta ensembles in the regime where $\beta n = const$ as $n \to \infty$. The results are (1) Gaussian fluctuations for linear statistics of the eigenvalues, and (2) Poisson convergence of the bulk statistics. (2) is an alternative proof of the result by F.~Benaych-Georges and S.~P\'ech\'e (2015) with the explicit form of the intensity measure.
