Мagnetized particle diffusion in a random electric field with jumping phase
Diffusion of charged particles across a constant magnetic field caused by random varying electric field is considered. The electric field is assumed to be a superposition of waves with a fixed frequency, various wave vectors and randomly jumping phase. The dependence of a diffusion coefficient on a...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | Diffusion of charged particles across a constant magnetic field caused by random varying electric field is considered. The electric field is assumed to be a superposition of waves with a fixed frequency, various wave vectors and
randomly jumping phase. The dependence of a diffusion coefficient on a field correlation time is calculated. The
effect of particle trapping which is more pronounced for a field with a low frequency of phase jumps is taken into
account. It is shown that the results of the statistical approach are consistent with the direct numerical simulation. |
