Collapse of very large amplitude ion waves
TL;DR: Recently, extremely large supersonic amplitude ion waves have been observed in simulations of backscatter instabilities, electron beam interactions, and large amplitude Langmuir waves, which break in an unconventional symmetrical x-type manner.

Decay Instability of the Ion-Beam Mode
TL;DR: Linearly stable slow-beam modes in ion-beam plasma systems are shown experimentally and theoretically to be unstable against parametric decay into subharmonic modes on the same (slow beam) branch as discussed by the authors.

Ponderomotive processes as proxies for breaking of ion acoustic solitary waves
Amar Kakad,Bharati Kakad +1 more
TL;DR: In this article, a fluid simulation of the ion acoustic solitary waves (IASWs) is performed to investigate the start time of the wave steepening and breaking process, and it is shown that a long wavelength perturbation in the electron and ion equilibrium densities evolves into two long wavelength IASWs.

Particle trapping and ponderomotive processes during breaking of ion acoustic waves in plasmas
TL;DR: In this paper, a particle-in-cell (PIC) simulation was performed to examine the effects of kinetic processes on the behavior of these proxies at the breaking of IASWs in plasmas.
