Compact spin-polarized positron accelerators play a major role in promoting significant positron application research, which typically require high acceleration gradients and polarization degrees, both of which, however, are still greatly challenging. Here, we put forward a spin-polarized positron a…

In hot dense plasma, the interaction between charged particles leads to the ionization potential depression (IPD), which further affects the physical properties of plasma, such as opacity and equation of state. The experiment of IPD of solid-density Al plasma has indicated that present theoretical m…

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.
