The objective of the paper is to discuss the results of theoretical and experimental studies and numerical simulations of following phenomena: the anomalous character of the breakdown conditions, the anomalous behavior ...
Electron heating and acceleration while magnetosphere substorm due to varying whistler wave phase velocity

Karas, V.I.; Potapenko, I.F. (Вопросы атомной науки и техники, 2007)

Some properties of chorus radiation while magnetosphere substorm are discussed. The influence of the hydro magnetic waves on the electron distribution function is studied by numerical simulations. A quasi-linear 2D in ...
Formation of steady - state nonequilibrium distribtions of the coulomb interacting - particles

Karas', V.I.; Potapenko, I.F. (Вопросы атомной науки и техники, 2003)

The collisional particle dynamics in such a system is investigated using a spatially homogeneous nonlinear collision integral in the Landau–Fokker–Planck form, which is a model Boltzmann colision integral for arbitrary ...
High energetic electron distribution tails for nonlinear collisional kinetic equation in the presence of heating

Potapenko, I.F.; Soboleva, T.K.; Krasheninnikov, S.I. (Вопросы атомной науки и техники, 2008)

The time-depended solutions of collisional electron kinetic equation with the heating term allowing the solutions in self-similar variables are considered. A broader class of the heating terms resulting in enhancement of ...
Kinetics of nonequilibrium electron-phonon system for semiconductors and metals in a strong electric field
