Scientific paper

Random magnetic fluctuations resembling Alfven waves are ubiquitously observed in laboratory, space and astrophysical plasmas. The issue of spectral cascade and plasma heating in Alfvenic turbulence is a major unsolved problem in space plasma physics. Gyrokinetic particle simulation is applied in this work to study the cascade and heating in Alfvenic turbulence with fully self-consistent nonlinear kinetic effects. A particle-in-cell code with gyrokinetic ions and fluid-kinetic hybrid electrons is being developed to study the coupling between shear Alfven wave and ion acoustic wave, which lead to energy exchange between waves and particles.
