Hyper Boris integrators for kinetic plasma simulations and their connection to 3D rotation representations

S. Zenitani, T. N. Kato

Particle-in-cell (PIC) simulation is one of the most important research tools in theoretical plasma physics. To solve the motion of charged particles, the Boris method (a.k.a. the…

Hyper Boris integrators for kinetic plasma simulations

Seiji Zenitani, Tsunehiko N. Kato

We propose a family of numerical solvers for the nonrelativistic Newton--Lorentz equation in kinetic plasma simulations. The new solvers extend the standard 4-step Boris procedure,…

Volume-preserving particle integrator based on exact flow of velocity for nonrelativistic particle-in-cell simulations

Tsunehiko N. Kato, Seiji Zenitani

We construct a particle integrator for nonrelativistic particles by means of the splitting method based on the exact flow of the equation of motion of particles in the presence of…

Multiple Boris integrators for particle-in-cell simulation

Seiji Zenitani, Tsunehiko N Kato

We construct Boris-type schemes for integrating the motion of charged particles in particle-in-cell (PIC) simulation. The new solvers virtually combine the 2-step Boris procedure a…

Evolution of three-dimensional Relativistic Ion Weibel Instability: Competition with Kink Instability

Makoto Takamoto, Yosuke Matsumoto, Tsunehiko N. Kato

In this paper, we report our recent findings on the relativistic Weibel instability and its nonlinear saturation by performing numerical simulations of collisionless plasmas. Analy…

Magnetic Field Saturation of the Ion Weibel Instability in Interpenetrating Relativistic Plasmas

Makoto Takamoto, Yosuke Matsumoto, Tsunehiko N. Kato

The time evolution and saturation of the Weibel instability at the ion Alfvén current are presented by ab initio particle-in-cell simulations. We found that the ion Weibel current…
