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 ...

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.

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.

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.

Particle transport in 3He-rich events: wave-particle interactions and particle anisotropy measurements [PDF]

open access: yesAnnales Geophysicae, 2002
Energetic particles and MHD waves are studied using simultaneous ISEE-3 data to investigate particle propagation and scattering between the source near the Sun and 1 AU.

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 ...

Wave-particle interaction in the Faraday waves

open access: yesThe 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

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 ...

A review of frequency chirping mechanism of chorus waves in the Earth's magnetosphere

open access: yes地球与行星物理论评, 2022
Whistler mode chorus waves are common and intense electromagnetic waves in the Earth's magnetosphere. They play a crucial role in magnetospheric electron dynamics by accelerating and scattering electrons over a wide energy range.
