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 … Tīmeklis2024. gada 26. sept. · We theoretically demonstrate that a system formed by two coupled graphene sheets enables a negative damping regime wherein graphene plasmons are pumped by a direct current.
