Wave-particle interaction in the Faraday waves

The European Physical Journal E, 2015
Wave motion in disordered Faraday waves is analysed in terms of oscillons or quasi-particles. The motion of these oscillons is measured using particle tracking tools and it is compared with the motion of fluid particles on the water surface. Both the real floating particles and the oscillons, representing the collective fluid motion, show Brownian-type

Wave–particle interactions in tokamaks

Nuclear Fusion
Abstract Transport consequences of the wave–particle interactions in the quasilinear plateau (QP) regime are presented. Eulerian approach is adopted to solve the drift kinetic equation that includes the physics of the nonlinear trapping (NT) and QP regimes.

Wave–particle interactions in rotating mirrors [PDF]

Physics of Plasmas, 2011
Wave–particle interactions in E×B rotating plasmas feature an unusual effect: particles are diffused by waves in both potential energy and kinetic energy. This wave–particle interaction generalizes the alpha channeling effect, in which radio frequency waves are used to remove alpha particles collisionlessly at low energy. In rotating plasmas, the alpha

Elastic and inelastic particles scattering by dust acoustic soliton. A new oscillatory process in dusty plasma

New Journal of Physics, 2021
The parameters of scattering (reflection) of charged particles by the leading edge of a dust acoustic soliton are analyzed. The soliton profile is calculated using the Sagdeev pseudopotential approach.

Analysis of dynamic levitation process of the particle chain in a nonlinear standing wave field

Scientific Reports
This research delves into the dynamic behavior of acoustic levitation of the particle chain in a nonlinear standing wave field. Experimental acoustic levitation control tests reveal bifurcation and jump phenomena during dynamic adjustments to resonant ...

Drift-compression waves propagating in the direction of energetic electron drift in the magnetosphere

Solar-Terrestrial Physics, 2017
As shown within the gyrokinetic framework, drift-compressional waves can propagate in the magnetosphere in the direction of energetic electron drift. The plasma is assumed to be composed of cold particles with an admixture of hot protons with a Maxwell ...

Synchronization of multiscale waveform focusing for rogue wave generation in dust acoustic wave turbulence

Physical Review Research, 2020
Rogue wave events (RWEs), uncertainly emerging localized extreme-amplitude events, ubiquitously occur in various nonlinear wave media. They have been mainly studied in the weakly disordered wave state with a single dominant wavelength scale. In this work,

Proton aurora and relativistic electron microbursts scattered by electromagnetic ion cyclotron waves

Frontiers in Astronomy and Space Sciences, 2022
Charged particle precipitation from Earth’s magnetosphere results in stunning displays of the aurora and energy transfer into the atmosphere. Some of this precipitation is caused by wave-particle interactions.

Nonlinear wave-particle interaction upstream from the Earth's bow shock [PDF]

Nonlinear Processes in Geophysics, 2000
Well-defined ring-like backstreaming ion distributions have been recently reported from observations made by the 3DP/PESA-High analyzer onboard the WIND spacecraft in the Earth's foreshock at large distances from the bow shock, which suggests a local ...

Planning for Observations of the Plasma Waves by Sounding Rockets in Antarctica

Antarctic Record, 1975
The plasma wave observations in the polar ionosphere consist of two categories; the first is for the emission due to the particle precipitation and the second is for the emissions that are thought to be generated in the magnetosphere as a result of the ...
