Relativistic electromagnetic solitons in magnetized laser-plasma interactions: A theoretical and parametric study

Abstract

Electromagnetic solitons created during the interaction of linearly polarized intense laser pulse with a magnetized plasma are investigated. To model the coupled laser-plasma system, fully relativistic hydrodynamic equations are used combined with Maxwell equations. The nonlinear Schrödinger equation is then acquired reflecting the formation of bright or dark solitons depending on the carrier wave frequency, in addition to the expression of the growth rate for modulational instabilities. To add a practical aspect to our study, a parametric analysis was conducted using values that are typical in intense laser-plasma interaction experiments. Our results closely matched the experimental observations, which contributes to the validation of our work.
