Energy-Preserving Coupling of Explicit Particle-In-Cell with Monte Carlo Collisions
Jean-Luc Vay, Justin Ray Angus, Olga Shapoval +3
The Particle-In-Cell (PIC) and Monte Carlo Collisions (MCC) methods are workhorses of many numerical simulations of physical systems. Recently, it was pointed out that, while the t…
Energy-momentum-conserving stochastic differential equations and algorithms for nonlinear Landau-Fokker-Planck equation
Yichen Fu, Justin R. Angus, Hong Qin +1
Coulomb collision is a fundamental diffusion process in plasmas that can be described by the Landau-Fokker-Planck (LFP) equation or the stochastic differential equation (SDE). Whil…
Moment-preserving Monte-Carlo Coulomb collision method for particle codes
Justin Ray Angus, Yichen Fu, Vasily Geyko +2
Binary-pairing Monte-Carlo methods are widely used in particle-in-cell codes to capture effects of small angle Coulomb collisions. These methods preserve momentum and energy exactl…
