Vlasov laser-plasma interaction simulations with a moving grid
Nicolas Crouseilles 1, Alain Ghizzo 1, Stéphanie Salmon 1, 2
(2007)

The present work focuses on the numerical resolution of a reduced $1$D 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 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 type equations. A semi-Lagrangian code is used to study the interaction of ultrashort electromagnetic pulse with plasma; however during the major part of the simulation, many of the grid points are wasted. We then introduce a dynamic mesh which allows us to consider the part of the phase space where the distribution function is not zero.
