S. Kartal et al., LOCALIZED STRUCTURES OF ELECTROMAGNETIC-WAVES IN HOT ELECTRON-POSITRON PLASMAS, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 53(4), 1996, pp. 4225-4228
The dynamics of relativistically strong electromagnetic (EM) wave prop
agation in a hot electron-positron plasma is investigated. The possibi
lity of finding localized stationary structures of EM waves is explore
d. It is shown that under certain conditions an EM wave forms a stable
localized solitonlike structure where plasma is completely expelled f
rom the region of the EM field location.
