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…

Discrete hypocoercive estimates for discontinuous Galerkin methods: application to the Vlasov-Poisson-Fokker-Planck system

Yi Cai, Alain Blaustein, Tao Xiong +1

We develop and analyze a class of structure-preserving discontinuous Galerkin schemes for the nonlinear Vlasov-Poisson-Fokker-Planck model, reformulated as a hyperbolic system thro…

Existence of solutions and uniform bounds for the stationary semiconductor equations with generation and ionic carriers

Dilara Abdel, Alain Blaustein, Claire Chainais-Hillairet +2

We consider a stationary drift-diffusion system with ionic charge carriers and external generation of electron and hole charge carriers. This system arises, among other application…

Derivation of the bacterial run-and-tumble kinetic model : quantitative and strong convergence results

Alain Blaustein

During the past century, biologists and mathematicians investigated two mechanisms underlying bacteria motion: the run phase during which bacteria move in straight lines and the tu…

A structure and asymptotic preserving scheme for the quasineutral limit of the Vlasov-Poisson system

Alain Blaustein, Giacomo Dimarco, Francis Filbet +1

In this work, we propose a new numerical method for the Vlasov-Poisson system that is both asymptotically consistent and stable in the quasineutral regime, i.e. when the Debye leng…

Longtime and chaotic dynamics in microscopic systems with singular interactions

Alexis Béjar-López, Alain Blaustein, Pierre-Emmanuel Jabin +1

This paper investigates the long time dynamics of interacting particle systems subject to singular interactions. We consider a microscopic system of interacting point particles…
