A Nonlinear PIC Algorithm for High Freqency Waves In Magnetized Plasmas Based on Gyrocenter Gauge Kinetic Theory
Authors: Jian Liu, Zhi Yu and Hong Qin
Abstract:
Numerical methods based on gyrocenter gauge kinetic theory are suitable for rst principle simu-
lations of high frequency waves in magnetized plasmas. The f gyrocenter gauge PIC simulation for
linear rf wave has been previously realized. In this paper we further develop a full-f nonlinear PIC
algorithm appropriate for the nonlinear physics of high frequency waves in magnetized plasmas.
Numerical cases of linear rf waves are calculated as a benchmark for the nonlinear GyroGauge
code, meanwhile nonlinear rf-wave phenomena are studied. The technique and advantage of the
reduction of the numerical noise in this full-f gyrocenter gauge PIC algorithm are also discussed.
