Verification of Electromagnetic Fully-kinetic Symplectic Particle-in-cell Method in Microinstabilities Simulation of
Jianyuan Xiao, Jian liu
We present a symplectic electromagnetic fully-kinetic particle-in-cell simulation of microinstabilities in plasma, using parameters from the Cyclone Base Case [Dimits, et al., Phys…
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…
Bohm-like Neoclassical Transport in Highly Collisional Toroidal Plasmas with High Density Gradients
Jianyuan Xiao, Huishan Cai, Jian Liu +2
Conventional neoclassical theory in the Pfirsch-Schlüter regime fails to accurately model collision-induced transport in toroidal plasmas with high density gradients. In this scena…
Hybrid simulation of energetic particles interacting with magnetohydrodynamics using a slow manifold algorithm and GPU acceleration
Chang Liu, Stephen C. Jardin, Hong Qin +3
The hybrid method combining particle-in-cell and magnetohydrodynamics can be used to study the interaction between energetic particles and global plasma modes. In this paper we int…
High-order Field Theory and Weak Euler-Lagrange-Barut Equation for Classical Relativistic Particle-Field Systems
Peifeng Fan, Qiang Chen, Jianyuan Xiao
It is widely accepted that conservation laws, especially energy-momentum conservation, have fundamental importance for both classical and quantum systems in physics. A widely used…
Slow manifolds of classical Pauli particle enable structure-preserving geometric algorithms for guiding center dynamics
Jianyuan Xiao, Hong Qin
Since variational symplectic integrators for the guiding center was proposed [1,2], structure-preserving geometric algorithms have become an active research field in plasma physics…
