Nonlinear Landau Damping

Transport Theory and Statistical Physics, 2009
In this article, we report the mathematical details of a systematic analysis of the nonlinear Landau damping of longitudinal electrostatic waves propagating in a collisionless plasma. Many of the main results have been reported previously; unfortunately, major parts of the essential mathematical developments had to be omitted for various reasons ...

Nonlinear damping of zonal flows

Plasma Physics Reports, 2016
The modulatonal instability theory for the generation of large-scale (zonal) modes by drift modes has been extended to the second order including the effects of finite amplitude zonal flows, ϕq. The nonlinear (second-order) sidebands are included in the perturbative expansion to derive the nonlinear equation for the evolution of ϕq.

Harmonic Oscillators with Nonlinear Damping

International Journal of Bifurcation and Chaos, 2017
Dynamical systems with special properties are continually being proposed and studied. Many of these systems are variants of the simple harmonic oscillator with nonlinear damping. This paper characterizes these systems as a hierarchy of increasingly complicated equations with correspondingly interesting behavior, including coexisting attractors, chaos ...

Damped nonlinear Schrödinger equation

The Physics of Fluids, 1976
High frequency electrostatic plasma oscillations described by the nonlinear Schrödinger equation in the presence of damping, collisional or Landau, are considered. At early times, Landau damping of an initial soliton profile results in a broader, but smaller amplitude soliton, while collisional damping reduces the soliton size everywhere; soliton ...
