Dynamics Of Dilute Gases At Equilibrium: From The Atomistic Description To Fluctuating Hydrodynamics

International audience; We derive linear fluctuating hydrodynamics as the low density limit of a deterministic system of particles at equilibrium. The proof builds upon previous results of the authors where the asymptotics of the covariance of the fl

International audience; We develop a rigorous theory of hard-sphere dynamics in the kinetic regime, away from thermal equilibrium. In the low density limit, the empirical density obeys a law of large numbers and the dynamics is governed by the Boltzm

Attractors for Two‐Dimensional Waves with Homogeneous Hamiltonians of Degree 0

Autor: Yves Colin de Verdière, Laure Saint-Raymond

Publikováno v: Communications on Pure and Applied Mathematics. 73:421-462

The density stratification in an incompressible fluid is responsible for the propagation of internal waves. In domains with topography, these waves exhibit interesting features. In particular, numerical and lab experiments show that, in two dimension

International audience; We review various contributions on the fundamental work of Lanford deriving the Boltzmann equation from hard-sphere dynamics in the low density limit. We focus especially on the assumptions made on the initial data and on how

International audience; The Fourier law of heat conduction describes heat diffusion in macroscopic systems. This physical law has been experimentally tested for a large class of physical systems. A natural question is to know whether it can be derive

LENARD-BALESCU CORRECTION TO MEAN-FIELD THEORY

Autor: Laure Saint-Raymond, Mitia Duerinckx

Publikováno v: Probability and Mathematical Physics

In the mean-field regime, the evolution of a gas of $N$ interacting particles is governed in first approximation by a Vlasov type equation with a self-induced force field. This equation is conservative and describes return to equilibrium only in the
