Non-linear control variate in δf particle-in-cell methods using symplectic neural networks
Victor Fournet, Martin Campos Pinto, Emmanuel Franck +1
We present a novel δf particle-in-cell (PIC) method for the kinetic simulation of electrostatic plasmas in which the bulk density, acting as a control variate, is evolved using sy…

Landau damping in mixed hyperbolic-kinetic systems and thick sprays
D. Bian, B. Després, V. Fournet +1
This article is devoted to the study of a model of thick sprays which combines the Vlasov equation for the particles and the barotropic compressible Euler equations to describe the…
