Suppressing spurious oscillations and particle noise in particle-in-cell simulations
Yuxi Chen, Hongyang Zhou, Gabor Toth
Particle-in-cell (PIC) simulations are essential for studying kinetic plasma processes, but they often suffer from statistical noise, especially in plasmas with fast flows. We have…

A Six-moment Multi-fluid Plasma Model
Zhenguang Huang, Gabor Toth, Bart van der Holst +2
We present a six-moment multi-fluid model, which solves the governing equations for both ions and electrons, with pressure anisotropy along and perpendicular to the magnetic field…

Gauss's Law Satisfying Energy-Conserving Semi-Implicit Particle-in-Cell Method
Yuxi Chen, Gabor Toth
The Energy Conserving Semi-Implicit Method (ECSIM) introduced by Lapenta (2017) has many advantageous properties compared to the classical semi-implicit and explicit PIC methods. M…
