A simple procedure for generating a Kappa distribution in PIC simulation
Seiji Zenitani
For kinetic modeling of plasma processes in space, a rejection-sampling procedure for generating a Kappa distribution in particle-in-cell (PIC) simulation is proposed. A Pareto dis…
Modifications to Swisdak (2013)'s rejection sampling algorithm for a Maxwell-Jüttner distribution in particle simulations
Seiji Zenitani
Modifications to Swisdak [Phys. Plasmas 20, 062110 (2013)]'s rejection sampling algorithm for drawing a Maxwell-Jüttner distribution in particle simulations are presented. Handy ap…
Outstanding questions and future research of magnetic reconnection
R. Nakamura, J. L. Burch, J. Birn +22
This short article highlights the unsolved problems of magnetic reconnection in collisionless plasma. The advanced in-situ plasma measurements and simulations enabled scientists to…
Loading loss-cone distributions in particle simulations
Seiji Zenitani, Shin'ya Nakano
Numerical procedures to generate random variates that follow loss-cone velocity distributions in particle simulations are presented. We propose a simple summation algorithm for the…
Exact Calculation of Nonideal Fields Demonstrates Dominance of Injection in Relativistic Reconnection
Samuel R. Totorica, Seiji Zenitani, Shuichi Matsukiyo +3
Magnetic reconnection is an important source of energetic particles in systems ranging from astrophysics to the laboratory. The large separation of spatiotemporal scales involved m…
Magnetic Reconnection and Associated Particle Acceleration in High-energy Astrophysics
Fan Guo, Yi-Hsin Liu, Seiji Zenitani +1
Magnetic reconnection occurs ubiquitously in the universe and is often invoked to explain fast energy release and particle acceleration in high-energy astrophysics. The study of re…
