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 … Tīmeklis2011. gada 5. jūl. · We also demonstrate that linear damping holds for initial perturbations in very rough spaces, for a linearly stable homogeneous state. This suggests that the contrasting dynamics in W s, p spaces with the critical power {s=1+\frac {1} {p}} is a truly nonlinear phenomena which can not be traced back to …

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 … TīmeklisIn this paper we establish exponential Landau damping in analytic regularity. The damping phenomenon is reinterpreted in terms of transfer of regularity between … Tīmeklismechanism for Landau damping of TCBI. Currently, in the EIC design, this damping of TCBI is demonstrated by sim-ulations [1] using a weak-strong beam-beam interaction at IP. This beam-beam induced damping effect is closely re-lated to the decoherence from the weak-strong beam-beam interaction [2]. On top of the coupling of the dipole … tapestry utilization management
