Numerical Simulations to the Vlasov-Poisson System with a Strong Magnetic Field
For computational plasma physics, this method enables efficient long-time simulations of magnetized plasmas by allowing large time steps without loss of accuracy.
The paper presents an efficient Particle-In-Cell algorithm for simulating the 3D Vlasov-Poisson system with a strong magnetic field, achieving accurate approximations of the drift-kinetic model with large time steps.
In this paper, we present an efficient Particle-In-Cell algorithm for the simulation of the three dimensional Vlasov-Poisson system in the presence of a strong external magnetic field. When the intensity of the magnetic field is sufficiently large and for any time step, the numerical scheme provides formally a consistent approximation of the drift-kinetic model, which corresponds to the asymptotic model. Numerical results show that this new Particle-In-Cell method is efficient and accurate large time steps.
