Abstract

We consider 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, that is when the inverse temperature satisfies βNκ0\beta N \to \kappa \ge 0 as N+N\to+\infty. We show that under general conditions on the interaction and the potential, the local fluctuations are described by a Poisson point process in the large N limit. We present applications to Coulomb and Riesz gases on Rn\mathbb{R}^n for any n1n\ge 1, as well as to the edge behavior of β\beta-ensembles on R\mathbb{R}.
