Wave-particle-interaction in kinetic plasmas [PDF]

open access: yesComputer 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.

A new paradigm for fast and repetitive chirping of Alfvén eigenmodes

open access: yesNuclear Fusion, 2023
A novel 2D nonlinear dynamical paradigm is constructed to interpret the fast and repetitive frequency chirping and amplitude oscillation of Alfvén eigenmodes excited by energetic particles in fusion plasmas as observed in global gyrokinetic simulations ...

A comparison study between observations and simulation results of Barghouthi model for O+ and H+ outflows in the polar wind [PDF]

open access: yesAnnales Geophysicae, 2011
To advance our understanding of the effect of wave-particle interactions on ion outflows in the polar wind region and the resulting ion heating and escape from low altitudes to higher altitudes, we carried out a comparison between polar wind ...

Magnetospheric Plasma Systems Science and Solar Wind Plasma Systems Science: The Plasma-Wave Interactions of Multiple Particle Populations

open access: yesFrontiers in Astronomy and Space Sciences, 2021
Building upon the research legacies of Peter Gary and Richard Thorne, this perspective discusses a plasma-system picture wherein multiple ion and electron populations interact with each other via multiple types of plasma waves.

Current drive by high intensity, pulsed, electron cyclotron wave packets [PDF]

open access: yesEPJ Web of Conferences, 2019
The nonlinear interaction of electrons with a high intensity, spatially localized, Gaussian, electro-magnetic wave packet, or beam, in the electron cyclotron range of frequencies is described by the relativistic Lorentz equation.

Finite element investigation on the wave-particle interactions in ultrasonic inspection of SiCp/Al composites

open access: yesMaterials Research Express, 2020
While particulate-reinforced metal matrix composites are composed of two phase materials with dramatically different physical and mechanical properties, sound wave-particle interactions play an important role in their ultrasonic inspection tests.

Shallow trimers of two identical fermions and one particle in resonant regimes

open access: yesSciPost Physics, 2022
We consider two identical fermions interacting in the p-wave channel. Each fermion also interacts with another particle in the vicinity of an s-wave resonance.

Probing the Boundary between Classical and Quantum Mechanics by Analyzing the Energy Dependence of Single-Electron Scattering Events at the Nanoscale

open access: yesNanomaterials, 2023
The relation between the energy-dependent particle and wave descriptions of electron–matter interactions on the nanoscale was analyzed by measuring the delocalization of an evanescent field from energy-filtered amplitude images of sample/vacuum ...

Characteristics of flux-time profiles, temporal evolution, and spatial distribution of radiation-belt electron precipitation bursts in the upper ionosphere before great and giant earthquakes

open access: yesAnnals of Geophysics, 2012
<p>The analysis of energetic electron observations made by the DEMETER satellite reveals that radiation belt electron precipitation (RBEP) bursts are observed in general several (~1-6 days) before a large (M &gt; 6.5) earthquake (EQ) in the ...
