Collisionless plasma definition
WebMar 9, 2024 · 2. Mechanisms and Pathways in Turbulence. In plasma physics, candidate dissipation mechanisms are often based on linear Vlasov theory. In this approach, largely based on laboratory plasma studies, solutions for perturbations about an assumed equilibrium give rise to wave modes, damping rates, and instabilities. WebApr 3, 2024 · The behavior of fundamental plasma processes, such as magnetic reconnection, plasma turbulence, and collisionless shocks—all of which, at a basic level, couple the large-scale fluid dynamics to the small-scale kinetic dynamics—are, thus, intrinsically linked to the collisionless dynamics in these systems.
