The physics of isolated plasma potential structures sustained by a deficit of phase-space
density on trapped orbits, commonly known as electron or ion holes, is reviewed. The …

Grid-based kinetic models are promising in that the numerical noise inherent in particle-
based methods is essentially eliminated. Here, we call such grid-based techniques a direct …

Notably, solitary waves that emerge from the nonlinear properties of plasmas are the main
focus of many current studies of localized disturbances in both laboratory and astrophysical …

We investigate the nonlinear resonant wave-particle interactions including the effects of
particle (phase) trapping, detrapping, and scattering by high-amplitude coherent waves …

Kinetic Vlasov simulations of one-dimensional finite amplitude Electron Plasma Waves are
performed in a multi-wavelength long system. A systematic study of the most unstable linear …

The nonlinear frequency shift is derived in a transparent asymptotic form for intense
Langmuir waves in general collisionless plasma. The formula describes both fluid and …

A first-principle variational approach to adiabatic collisionless plasma waves is described.
The focus is made on one-dimensional electrostatic oscillations, including phase-mixed …

Electron and ion holes are highly stable nonlinear structures met omnipresently in driven
collisionless hot plasmas. A mechanism destabilizing small perturbations into holes is …

A reductive perturbation approach was used for both linear and nonlinear analysis, and the
related Quantum Zakharov–Kuznetsov (QZK) equation is deduced for dense quantum …

The bunching instability of particles trapped in Langmuir waves is studied using Vlasov
simulations. A measure of particle bunching is defined and used to extract the growth rate …
