Emergence of a Poisson process in weakly interacting particle systems

Probability 2025-06-18 v2

Abstract

We consider the Gibbs measure of a general interacting particle system for a certain class of ``weakly interacting" kernels. In particular, we show that the local point process converges to a Poisson point process as long as the inverse temperature β\beta satisfies N1βN12N^{-1} \ll \beta \ll N^{-\frac{1}{2}}, where NN is the number of particles. This expands the temperature regime for which convergence to a Poisson point process has been proved.
