| Abstract: | The generation of relativistic electromagnetic solitons in plasma with spatiotemporal density modulation is investigated.
When two counter-propagating laser pulses overlap in underdense plasma, the interaction between the pulses and plasma modulates
the electron and ion densities resulting in localized, stable, long-living relativistic electromagnetic solitons. They are
caused by the Stimulated Raman Scattering instability. The dependence of the formation of relativistic electromagnetic solitons
on the ion motion, plasma parameters, and laser parameters is studied by particle-in-cell simulations as well. |
