Self-trapping of strong electromagnetic beams in relativistic plasmas
Interaction of an intense electromagnetic (EM) beam with hot relativistic
plasma is investigated. It is shown that the thermal pressure brings about a
fundamental change in the dynamics - localized, high amplitude, EM field
structures, not accessible to a cold (but relativisic) plasma, can now be
formed under well- defined conditions. Examples of the trapping of EM beams in
self-guiding regimes to form stable 2D solitonic structures in a pure e-p
plasma are worked out.Comment: 9 pages, 6 figure
Localized structures of electromagnetic waves in hot electron-positronplasmas
The dynamics of relativistically strong electromagnetic (EM) wave propagation
in hot electron-positron plasma is investigated. The possibility of finding
localized stationary structures of EM waves is explored. It is shown that under
certain conditions the EM wave forms a stable localized soliton-like structures
where plasma is completely expelled from the region of EM field location.Comment: 14 pages, LaTeX, 1 figure can be obtained upon request through email
