Parallel and perpendicular diffusion coefficients of energetic charged particles with adiabatic focusing
J. F. Wang, G. Qin
It is very important to understand stochastic diffusion of energetic charged particles in non-uniform background magnetic field in plasmas of astrophysics and fusion devices. Using…
Modulation of Galactic Cosmic Rays in the Inner Heliosphere, Comparing with PAMELA Measurements
Gang Qin, Zhenning Shen
We develop a numerical model to study the time-dependent modulation of galactic cosmic rays (GCRs) in the inner heliosphere. In the model a time-delayed modified Parker heliospheri…
Magnetic field line random walk in two-dimensional dynamical turbulence
J. F. Wang, G. Qin, Q. M. Ma +2
The field line random walk (FLRW) of magnetic turbulence is one of the important topics in plasma physics and astrophysics. In this article by using the field line tracing method m…
Numerical simulations of particle acceleration at interplanetary quasi-perpendicular shocks
F. -J. Kong, G. Qin, L. -H. Zhang
Using test particle simulations we study particle acceleration at highly perpendicular () shocks under conditions of modeling magnetic turbulence. We adopt a b…
Perpendicular diffusion coefficient of cosmic rays in the presence of weak adiabatic focusing
J. F. Wang, G. Qin, Q. M. Ma +2
The influence of adiabatic focusing on particle diffusion is an important topic in astrophysics and plasma physics. In the past several authors have explored the influence of along…
