Landau damping of spin waves in trapped Boltzmann gases
Ultracold gas boltzmann spatial dependence
2014/12/20
A semiclassical method is used to study Landau damping of transverse pseudo-spin waves in harmonically trapped ultracold gases in the collisionless Boltzmann limit. In this approach, the time evolutio...
Samll BGK waves and nonlinear Landau damping (higher dimensions)
Samll BGK waves nonlinear Landau damping

Consider Vlasov-Poisson system with a fixed ion background and periodic condition on the space variables, in any dimension d 2. First, we show that for general homogeneous equilibrium and any period...
The role of nonlinear Landau damping and the bounced motion of protons in the formation of dissipative structures in the solar wind plasma
