Vi. Berezhiani et al., RELATIVISTIC SOLITARY WAVE IN AN ELECTRON-POSITRON PLASMA, Physical review. E, Statistical physics, plasmas, fluids, and related interdisciplinary topics, 48(5), 1993, pp. 180003252-180003255
Relativistic solitary-wave propagation is studied in a cold electron-p
ositron plasma embedded in an external arbitrary strong magnetic field
. The exact, analytical, solitonlike solution corresponding to a local
ized, purely electromagnetic pulse with an arbitrarily large amplitude
is found.
