SUMMARY:Workshop / Seminar:Quantitative propagation of chaos and universality for asymmetric Langevin spin glass dynamics
DESCRIPTION:We obtain quantitative estimates on quenched propagation of chaos for Langevin spin glass dynamics with i.i.d. disorder. Prior work in the case of Gaussian disorder established the qualitative convergence of the law of a single spin to a deterministic McKean--Vlasov limit. We prove convergence rates in expected Wasserstein distance and quantitative concentration rates for Lipschitz observables under the assumption that the disorder satisfies the T_2 inequality. The proof uses a coupling argument\, together with techniques from concentration of measure\, filtering theory\, and Malliavin calculus.
