چکیده
The subject matter of this paper concerns the numerical approximation of reduced Vlasov-Maxwell models by semi-Lagrangian schemes. Such reduced systems have been introduced recently in the literature for studying the laser-plasma interaction. We recall the main existence and uniqueness results on these topics, we present the semi-Lagrangian scheme and finally we establish the convergence of this scheme.

Vlasov laser-plasma interaction simulations in the relativistic regime with a moving grid
The present work focuses on the numerical resolution of a reduced 1D VlasovMaxwell system introduced recently in the physical literature for studying laser-plasma interaction. This system can be seen as a standard Vlasov equation in which the force term is split into two terms: the classical electrostatic field obtained from the Poisson’s equation and a magnetic term evolving through Maxwell’s ...
متن کاملComparison of numerical interpolation schemes for one-dimensional electrostatic Vlasov code
We discuss numerical interpolation schemes used in Vlasov codes. An improved conservative semi-Lagrangian scheme is compared with the latest nonconservative and conservative schemes for a long run-time nonlinear problem of the beam-plasma interaction with respect to the mass and energy conservations.
متن کاملOn the harmonic Boltzmannian waves in laser-plasma interaction
We study the permanent regimes of the reduced Vlasov–Maxwell system for laser-plasma interaction. A non-relativistic and two different relativistic models are investigated. We prove the existence of solutions where the distribution function is Boltzmannian and the electromagnetic variables are time-harmonic and circularly polarized.
متن کاملAnalysis of a new class of forward semi-Lagrangian schemes for the 1D Vlasov Poisson equations
The Vlasov equation is a kinetic model describing the evolution of a plasma which is a globally neutral gas of charged particles. It is self-consistently coupled with Poisson’s equation, which rules the evolution of the electric field. In this paper, we introduce a new class of forward Semi-Lagrangian schemes for the Vlasov-Poisson system based on a Cauchy Kovalevsky (CK) procedure for the nume...
متن کاملGlobal Solutions for the One-dimensional Vlasov-maxwell System for Laser-plasma Interaction
We analyse a reduced 1D Vlasov–Maxwell system introduced recently in the physical literature for studying laser-plasma interaction. This system can be seen as a standard Vlasov equation in which the field is split in two terms: an electrostatic field obtained from Poisson’s equation and a vector potential term satisfying a nonlinear wave equation. Both nonlinearities in the Poisson and wave equ...
