Title: Large deviation principles for singular Riesz-type diffusive flows
Abstract:
Many of the most interesting mean-field interacting particle systems
involve Riesz or inverse-power type interactions. However, it is only
relatively recently that these systems have been shown to satisfy
mean-field convergence in full generality. That is, as the number of
particles increases, the empirical measures converge to a limiting
equation. Despite this progress, proving these systems satisfy large
deviation principles remains a significant open problem. Most known
results, motivated by random matrix theory, focus on particles with
logarithmic repulsion in 1D and are not easily adapted to more singular
interactions. In this talk, I will discuss my recent work, where I
combine modulated energy methods and hydrodynamic techniques to derive
local large deviation estimates for repulsive, sub-Coulomb Riesz
interacting systems.
