[PEM17-06] Particle scattering in decaying magnetosonic-whistler mode turbulence
Keywords:kinetic plasma turbulence, magnetosonic-whistler mode wave, Particle-In-Cell simulation
In this study we focus on ion and electron scattering through the forward cascade of magnetosonic/whistler mode turbulence. Two-dimensional particle-in-cell simulation demonstrates nonlinear development of magnetosonic-whistler turbulence at scales larger than ion kinetic scales. It is shown that anisotropic magnetosonic-whistler turbulence cascades to smaller scales following dispersion relation of highly-oblique propagating whistler mode waves, which involves intermittent large-amplitude magnetosonic waves. The magnetosonic waves scatter ions and electrons in the directions perpendicular and parallel to the background magnetic field respectively. Our simulation suggests that ions and electrons in magnetosonic-whistler mode turbulence are accelerated/heated by not only Landau and cyclotron resonance at electron kinetic scales but also nonlinear fluctuations generated at sub-ion kinetic scales.
