We discuss the parametric instabilities of large-amplitude parallel propagating Alfvén waves using the 2-D PIC simulation code. First, we confirmed the results in the past study [Sakai et al., 2005]… (More)

Dispersion relation and nonlinear evolution of the parametric instabilities of circularly polarized Alfvén waves in a relativistic electron-positron plasma are investigated by theoretical and… (More)

We have performed 3 one-dimensional full particle electromagnetic simulations of a quasi-perpendicular shock with the same Alfvén Mach number MA∼5, shock normal-magnetic field angle 2Bn=87 and ion… (More)

Cross-scale coupling between fluid dynamics and particle kinetics at perpendicular collisionless shocks is an issue of space plasma physics. The influence of shock-front ripples to the dynamics of… (More)

Ring distribution of particles in a plasma in momentum space generates electromagnetic waves via cyclotron resonance. In addition to the well-known temperature anisotropy driven instability with… (More)

Diffusive shock acceleration (Fermi acceleration) of cosmic rays in a system containing two shock waves is investigated using test particle simulations and analysis of the diffusion convection… (More)

Properties of low beta quasi-perpendicular shocks for various ion-to-electron mass ratios are studied by using a one dimensional full particle simulation code. It is shown that the shock reformation… (More)
