Wave-Particle Interaction in the Ionosphere and magnetosphere

open access: yesAntarctic Record, 1979
Wave-particle interactions that are important processes for the control of the electromagnetic states in the earth's magnetosphere are surveyed relatingto the auroral zone that is the most suitable window to clarify the various aspects of wave-particle ...

Using MEPED observations to infer plasma density and chorus intensity in the radiation belts

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Efforts to model and predict energetic electron fluxes in the radiation belts are highly sensitive to local wave-particle interactions. In this study, we use multi-point measurements of precipitating and trapped electron fluxes to investigate the dynamic

Conditional wave theory of environmental interactions with a quantum particle

open access: yesPhysical Review Research, 2020
We present an alternative formulation of quantum decoherence theory using conditional wave theory (CWT), which was originally developed in molecular physics (also known as exact factorization methods). We formulate a CWT of a classic model of collisional

Landau Damping of Langmuir Waves: An Alternative Derivation

open access: yesPhysics, 2021
In this paper, a discussion of the Landau damping of Langmuir waves is presented together with a simple derivation which does not require the application of methods of complex analysis.

Wave-Particle Interactions in Astrophysical Plasmas

open access: yesGalaxies
Dissipation 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.

Wave–particle interactions in tokamaks

open access: yesNuclear Fusion
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.

A quantitative model for cyclotron wave-particle interactions at the plasmapause [PDF]

open access: yesAnnales Geophysicae, 1998
The formation of a zone of energetic electron precipitation by the plasmapause, a region of enhanced plasma density, following energetic particle injection during a magnetic storm, is analyzed.

Equations of Motion Near Cyclotron Resonance

open access: yesFrontiers in Astronomy and Space Sciences, 2022
This work compares several versions of the equations of motion for a test particle encountering cyclotron resonance with a single, field-aligned whistler mode wave.

Analytical results for phase bunching in the pendulum model of wave-particle interactions

open access: yesFrontiers in Astronomy and Space Sciences, 2022
Radiation belt electrons are strongly affected by resonant interactions with cyclotron-resonant waves. In the case of a particle passing through resonance with a single, coherent wave, a Hamiltonian formulation is advantageous.

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

open access: yesFrontiers 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.
