Landau damping
Tīmeklis2004. gada 20. janv. · The damping of a longitudinal plasma wave of finite amplitude is considered. It is shown that the Landau result is the first term in a systematic expansion in a small parameter, and the corrections for finite wave amplitude are shown to be fifth order in the small parameter. The contributions to the damping from particles with … Tīmeklis2016. gada 20. janv. · The mechanism of Landau damping is observed in various systems from plasma oscillations to accelerators. Despite its widespread use, some …

Tīmeklis2024. gada 28. dec. · We establish the possibility of Landau damping for gravitational scalar waves which propagate in a non-collisional gas of particles. In particular, under the hypothesis of homogeneity and isotropy, we describe the medium at the equilibrium with a Jüttner–Maxwell distribution, and we analytically determine the damping rate … Tīmeklis2016. gada 21. apr. · Landau damping is a collisionless relaxation mechanism discovered by Landau (after preliminary works of Vlasov ) predicting the decay of …

Landau damping of ion‐acoustic waves is only slightly affected by the presence of a high‐energy tail, but is strongly dependent on the ion temperature.

The region which contains +i1 corresponds to instabil-ity. Thus, one can substitute a simpler computation (find-ing discrete eigenvalues) for a more complex … 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.
