摘要: The present paper investigates the physics of electron firehose instability propagating parallel to direction ambient magnetic field vector, by means particle-in-cell simulation and macroscopic quasilinear kinetic theory. is excited when temperature exceeds perpendicular temperature, T∥e>T⊥e, under high beta conditions. A recent [Sarfraz et al., Phys. Plasmas 24, 012907 (2017)] formulated theory assuming that proton velocity distribution functions can be approximately described bi-Maxwellian forms for all times but allowing dynamical changes in temperatures as well wave intensity. examines validity such an approach making direct comparison against simulation. It shown provides a qualitative description nonlinear phase i...
