We investigate parallel electron acceleration due to inertial Alfven wave pulses in the presence of Lorentzian ( kappa) distribution functions which possess high-energy tails. A linear kinetic dispersion relation for inertial Alfven waves is derived whose solutions are used to guide the analysis...

Using 1D Vlasov drift-kinetic computer simulations, it is shown that electron trapping in long period standing shear Alfvén waves (SAWs) provides an efficient energy sink for wave energy that is much more effective than Landau damping. It is also suggested that the plasma environment of low...

We present self-consistent kinetic simulations of the electron response to finite duration shear Alfven wave pulses in a magnetized plasma. In Earth's magnetosphere, the evidence suggests that parallel electric fields in inertial scale shear Alfven waves can accelerate electrons in the...
