Wave-Energy Partition Governs Weak Collisional Damping in Cold Plasmas
Yanzeng Zhang, Xianzhu Tang, Ge Zhuang
Weak dissipation can control wave propagation, mode competition, and instability thresholds in plasmas, yet the physical origin of large branch-to-branch differences in collisional…

A conservative, implicit solver for 0D-2V multi-species nonlinear Fokker-Planck collision equations
Yanpeng Wang, Jianyuan Xiao, Yifeng Zheng +3
In this study, we present an optimal implicit algorithm specifically designed to accurately solve the multi-species nonlinear 0D-2V axisymmetric Fokker-Planck-Rosenbluth (FPR) coll…

Relaxation model for a homogeneous plasma with spherically symmetric velocity space
Yanpeng Wang, Jianyuan Xiao, Xianhao Rao +3
We derive the transport equations from the Vlasov-Fokker-Planck equation when the velocity space is spherically symmetric. The Shkarofsky's form of Fokker-Planck-Rosenbluth collisi…
