Abstract:The traveling relativistic solitons in electron-positron hot plasmas is investigated. The influence of the positron motion on the soliton's structure is taken into account. A closed set of equations consisting of scalar potential, vector potential and enthalpy in ultra-relativistic regime is presented; symmetric and antisymmetric solitary solutions are obtained numerically. The nonlinear dispersion relation of the system is derived in the quasi-neutral limit for the purpose of analyzing the modulational instab… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
