In this paper, the authors studied the edge statistics of the Gaussian ensemble and proved that the associated extreme point process converges in distribution to a Poisson point process as the inverse temperature tends to zero as the number of particles tends to infinity.
Abstract
We study the asymptotic edge statistics of the Gaussian $\beta$-ensemble, a collection of $n$ particles, as the inverse temperature $\beta$ tends to zero as $n$ tends to infinity. In a certain decay regime of $\beta$, the associated extreme point process is proved to converge in distribution to a Poisson point process as $n\to +\infty$. We also extend a well known result on Poisson limit for Gaussian extremes by showing the existence of an edge regime that we did not find in the literature.

Poisson statistics for Gibbs measures at high temperature

TL;DR: In this paper, a gas of N particles with a general two-body interaction and confined by an external potential in the mean field or high temperature regime is considered, and the local fluctuations are described by a Poisson point process in the large N limit.

Poisson statistics for beta ensembles on the real line at high temperature

TL;DR: In this paper, the authors studied the local behavior of the beta ensembles on the real line in a high temperature regime and showed that the local statistics around any fixed reference energy converges weakly to a homogeneous Poisson point process.

Large Deviations Principle for the Largest Eigenvalue of the Gaussian $$\beta $$β-Ensemble at High Temperature

TL;DR: In this article, the largest particle satisfies a large deviations principle in the Gaussian ensemble when the number of particles scales with n such that it converges in probability to 2, the rightmost point of the semicircle law.

Continuum limits of random matrices and the Brownian carousel

TL;DR: The authors showed that at any location away from the spectral edge, the eigenvalues of the Gaussian unitary ensemble and its general β siblings converge to Sine β, a translation invariant point process.
