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.

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.

The strong Langmuir turbulence spectra in weakly relativistic plasma

AIP Advances, 2019
The spectral characteristics of strong Langmuir turbulence in weakly relativistic plasma is analyzed. The temporal evolutions of the turbulence energy density spectra are obtained by perfoyming the fast Fourier transformations on weakly relativistic ...

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.
