Intrinsic local Gauss's law preserving PIC method: A self-consistent field-particle update scheme for plasma simulations
Zhonghua Qiao, Zhenli Xu, Qian Yin +1
In order to perform physically faithful particle-in-cell (PIC) simulations, the Gauss's law stands as a critical requirement, since its violation often leads to catastrophic errors…

Finite-Difference Approximations and Local Algorithm for the Poisson and Poisson-Boltzmann Electrostatics
Bo Li, Qian Yin, Shenggao Zhou
We study finite-difference approximations of both Poisson and Poisson-Boltzmann (PB) electrostatic energy functionals for periodic structures constrained by Gauss' law and a class…
