Detection of ultrafast electron energization by whistler-mode chorus waves in the magnetosphere of Earth

Scientific Reports
Electromagnetic whistler-mode chorus waves are a key driver of variations in energetic electron fluxes in the Earth’s magnetosphere through the wave-particle interaction.

Properties of relativistic electron precipitation: a comparative analysis of wave-induced and field line curvature scattering processes

Frontiers in Astronomy and Space Sciences
We analyze the properties of relativistic (>700 keV) electron precipitation (REP) events measured by the low-Earth-orbit (LEO) POES/MetOp constellation of spacecraft from 2012 through 2023.

Nonlinear Coupling Between Whistler‐Mode Chorus and Electron Cyclotron Harmonic Waves in the Magnetosphere

Geophysical Research Letters, 2018
Electromagnetic whistler‐mode chorus and electrostatic electron cyclotron harmonic (ECH) waves can contribute significantly to auroral electron precipitation and radiation belt electron acceleration.

THEMIS Observations of Particle Acceleration by a Magnetosheath Jet‐Driven Bow Wave

Geophysical Research Letters, 2019
Localized magnetosheath jets with high dynamic pressure are frequently observed downstream of Earth's bow shock. When such a fast magnetosheath jet compresses the ambient magnetosheath plasma, an earthward compressional bow wave could form.

Velocity-space tomography of MeV-range fast-ion distributions in JET using wave–particle interaction priors

Nuclear Fusion
The fast-ion distribution function in fusion plasmas can only be measured indirectly by solving an ill-posed inverse problem. The inversion being ill-posed necessitates regularisation of the problem to ensure that the reconstruction of the fast-ion ...

The challenge to understand the zoo of particle transport regimes during resonant wave-particle interactions for given survey-mode wave spectra

Frontiers in Astronomy and Space Sciences
Quasilinear theories have been shown to well describe a range of transport phenomena in magnetospheric, space, astrophysical and laboratory plasma “weak turbulence” scenarios.

Electron wave-spin qubit

Journal of Physics Communications
As a continuation of our earlier investigations into electron wave–spin, we analyze the electron spin and its qubit in a cavity by treating the electron as a physical wave obeying the Dirac equation.

Cross‐Scale Interactions Between ULF Waves, VLF Waves, and Electrons

Geophysical Research Letters
Wave‐particle interactions are essential for energy transport in the magnetosphere. In this study, we investigated an event during which electrons interact simultaneously with waves in different scales, using data from the Magnetospheric Multiscale ...

Significance of Wave-Particle Interaction Analyzer for direct measurements of nonlinear wave-particle interactions

Significance of Wave-Particle Interaction Analyzer for direct measurements of nonlinear wave-particle interactions
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.
