Numerical simulations and their theoretical interpretation of the formation of standing electromagnetic solitons produced in a regime of pulsating stimulated Brillouin scattering are presented. The localized field structures are stable, long-living entities and their physical properties are in very good agreement with theoretical predictions of electromagnetic solitons in a hot and dense plasma. They are the final outcome of a specific mode-coupling regime that can be attained for high laser intensities via the transient excitation of kinetic electrostatic nonlinear electron modes.

Abstract
Numerical simulations and their theoretical interpretation of the formation of standing electromagnetic solitons produced in a regime of pulsating stimulated Brillouin scattering are presented. The localized field structures are stable, long-living entities and their physical properties are in very good agreement with theoretical predictions of electromagnetic solitons in a hot and dense plasma. They are the final outcome of a specific mode-coupling regime that can be attained for high laser intensities via the transient excitation of kinetic electrostatic nonlinear electron modes.File in questo prodotto:
