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

A Blaustein, F Filbet - Journal of Computational Physics, 2024 - Elsevier
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 …

-Hypocoercivity and Large Time Asymptotics of the Linearized Vlasov–Poisson–Fokker–Planck System

Propagator norm and sharp decay estimates for Fokker-Planck equations with linear drift

A Arnold, C Schmeiser, B Signorello - arXiv preprint arXiv:2003.01405, 2020 - arxiv.org
We are concerned with the short-and large-time behavior of the $ L^ 2$-propagator norm of
Fokker-Planck equations with linear drift, ie $\partial_t f=\mathrm {div} _ {x}{(D\nabla_x f+ …

Diffusive limit of the vlasov–poisson–fokker–planck model: Quantitative and strong convergence results

This work tackles the diffusive limit for the Vlasov–Poisson–Fokker–Planck model. We derive
a priori estimates which hold without restriction on the phase-space dimension and propose …

Well-posedness and long-time behavior for self-consistent Vlasov-Fokker-Planck equations with general potentials

Fokker-Planck equation with external confinement potential and nonlinear self-consistent …

Long Wave Asymptotics for the Vlasov–Poisson–Landau Kinetic Equation

AV Bobylev, IF Potapenko - Journal of Statistical Physics, 2019 - Springer
The work is devoted to some mathematical problems of dynamics of collisional plasma. The
difficulty is that in plasma case we have at least three different length scales: Debye radius …

Anisotropic boltzmann-gibbs dynamics of strongly magnetized vlasov-fokker-planck equations

M Herda, LM Rodrigues - arXiv preprint arXiv:1610.05138, 2016 - arxiv.org
We consider various sets of Vlasov-Fokker-Planck equations modeling the dynamics of
