A structure and asymptotic preserving scheme for the Vlasov-Poisson-Fokker-Planck model

Alain Blaustein, Francis Filbet

We propose a numerical method for the Vlasov-Poisson-Fokker-Planck model written as an hyperbolic system thanks to a spectral decomposition in the basis of Hermite functions with r…

On a discrete framework of hypocoercivity for kinetic equations

Alain Blaustein, Francis Filbet

We propose and study a fully discrete finite volume scheme for the Vlasov-Fokker-Planck equation written as an hyperbolic system using Hermite polynomials in velocity. This approac…

Asymptotically preserving particle methods for strongly magnetizedplasmas in a torus

Francis Filbet, Luis Miguel Miguel Rodrigues

We propose and analyze a class of particle methods for the Vlasov equation with a strong external magnetic field in a torus configuration. In this regime, the time step can be subj…

On the convergence of discontinuous Galerkin/Hermite spectral methods for the Vlasov-Poisson system

Marianne Bessemoulin-Chatard, Francis Filbet

We prove the convergence of discontinuous Galerkin approximations for the Vlasov-Poisson system written as an hyperbolic system using Hermite polynomials in velocity. To obtain sta…

Fokker-planck Multi-species Equations In The Adiabatic Asymptotics

Francis Filbet, Claudia Negulescu

The main concern of the present paper is the study of the multi-scale dynamics of thermonuclear fusion plasmas via a multi-species Fokker-Planck kinetic model. One of the goals is…

Concentration phenomena in Fitzhugh-Nagumo's equations: A mesoscopic approach

Alain Blaustein, Francis Filbet

We consider a spatially extended mesoscopic FitzHugh-Nagumo model with strong local interactions and prove that its asymptotic limit converges towards the classical nonlocal reacti…
