It is shown that the Landau damping of electron plasma waves (EPWs) is significantly enhanced in a transverse magnetic field with tens of teslas due to a strong modification of the electron velocity distribution function formed in the two-plasmon-decay (TPD) process. The Landau damping even in the r…

The dynamics of electrons in space plasmas, such as the earth’s radiation belts, are affected by the presence of wave turbulence, even when a resonance condition is not satisfied. The authors propose an expression to describe this resonance broadening effect, and find that it compares well with test particle simulation results. The study is applied to whistler-mode chorus waves in the radiation belt’s electrons, but can be easily extended to a wide range of systems.

A considerable number of semiempirical and first-principles models have been created to describe the dynamic response of a collisionally damped charged-particle system. However, known challenges persist for established dynamic structure factors (DSFs), dielectric functions, and conductivities. For i…

Lightning is a source of x-ray and gamma radiation, one of the most powerful natural photon emissions on Earth. In the paper, based on recently published measurement data, we explain the experimental results and state that the observed high-energy radiation is generated by synchrotron and cyclotron …

The existence and stability criteria of one-dimensional ion-acoustic solitons in a quantum cold, over-dense plasma are investigated through theoretical and numerical analyses. Within the quantum magnetohydrodynamic dominant regime, distinct governing equations are employed for spin-up and spin-down …

Positron creation and acceleration is one of the major challenges for constructing future lepton colliders. On the one hand, conventional technology can provide a solution, but at a prohibitive cost and scale. On the other hand, alternative, reduced-scale ideas for positron beam generation could bri…
