Dynamics of spatially overlapping flat top electromagnetic solitons in plasmas — •Sita Sundar — Christian-Albrechts-Universität Kiel

Interaction of ultra-intense laser with plasma exhibits a rich variety of interesting nonlinear phenomena. Numerical and asymptotic solu- tions describing the interactions of relativistically intense plane elec- tromagnetic waves and cold plasmas are of fundamental importance for nonlinear science and are considered to be a basic component of turbulence in plasmas. The numerical identification of solitons stim- ulated a renewed interest in developing an analytical model and in envisaging ways of detecting solitons experimentally. The inclusion of ion response in the relativistically intense electromagnetic laser pulse propagation in plasma yields certain distinct varieties of single peak solitonic structures. A falt-top slow moving structure is one such so- lution. Here, detailed characterization and numerical investigations on mutual interactions between two spatially overlapping electromagnetic flat-top solitons in plasma will be presented.
