Frontiers in Astronomy and Space Sciences, 2022 Wave particle interactions are known to be an efficient yet unquantified driver of the variability of particle populations in Earth’s magnetosphere, and their quantification and understanding through modelling has been a subject of ceaseless and extensive research during the last decades.

Wave-particle-interaction in kinetic plasmas [PDF]
Computer Physics Communications, 2014 Resonant scattering of energetic protons off magnetic irregularities is the main process in cosmic ray diffusion. The typical theoretical description uses Alfven waves in the low frequency limit. We demonstrate that the usage of Particle-in-Cell (PiC) simulations for particle scattering is feasible.

Wave-Particle Interactions in Astrophysical Plasmas
GalaxiesDissipation processes derived from the kinetic theory of gases (shear viscosity and heat conduction) are employed to examine the solar wind that interacts with planetary ionospheres. The purpose of this study is to estimate the mean free path of wave-particle interactions that produce a continuum response in the plasma behavior.

Significance of Wave-Particle Interaction Analyzer for direct measurements of nonlinear wave-particle interactions [PDF]
Annales Geophysicae, 2013 Abstract. In the upcoming JAXA/ERG satellite mission, Wave Particle Interaction Analyzer (WPIA) will be installed as an onboard software function. We study the statistical significance of the WPIA for measurement of the energy transfer process between energetic electrons and whistler-mode chorus emissions in the Earth's inner magnetosphere.

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

Direct observation of a “devil’s staircase” in wave-particle interaction [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2006 We report the experimental observation of a “devil’s staircase” in a time-dependent system considered as a paradigm for the transition to large-scale chaos in the universality class of Hamiltonian systems. A test electron beam is used to observe its non-self-consistent interaction with externally excited wave(s) in a traveling wave tube (TWT).

A new instrument for the study of wave-particle interactions in space: One-chip Wave-Particle Interaction Analyzer [PDF]
Earth, Planets and Space, 2009 Abstract Wave-particle interactions in a collisionless plasma have been analyzed in several past space science missions but direct and quantitative measurement of the interactions has not been conducted. We here introduce the Wave-Particle Interaction Analyzer (WPIA) to observe wave-particle interactions directly by calculating the inner ...

Wave–particle interactions in tokamaks
Nuclear FusionAbstract 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.
