Landau damping
Tīmeklis2024. gada 12. febr. · Landau damping in a collisionless plasma is a well-known example of wave particle interaction. In the past, this phenomenon was addressed for homogeneous equilibria in the linear and non-linear limit of the perturbation amplitude. However, in reality, equilibria are almost always inhomogeneous or non-uniform in … TīmeklisLandau damping is a kinetic plasma phenomenon that does not have a fluid or neutral gas analog since it involves the interaction of charged particles with wave electric …

The damping phenomenon is reinterpreted in terms of transfer of regularity … Tīmeklis2024. gada 1. janv. · Landau damping 1. Introduction A plasma system can be described by either microscopic kinetic theory that involves the dynamics of individual particles or macroscopic fluid equations. The kinetic theory can describe the distribution of particles in phase space.
