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…

A Binary Collision Method for Screened Coulomb Collisions in weakly and moderately coupled Plasmas
Justin Ray Angus, Johannes Johgan van de Wetering
A binary-pairing Monte Carlo collision method is presented here for screened Coulomb collisions in plasmas that is valid in the weakly and moderately coupled regimes. The method mo…

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…
