Nonlinear interaction of electron plasma waves with electron acoustic waves in plasmas

Nikhil Chakrabarti, Sudip Sengupta

Open publisher page 22 citations

Abstract

An analysis of interaction between two temperature electron species in the presence of static neutralizing ion background is presented. It is shown that electron plasma waves can nonlinearly interact with electron acoustic wave in a time scale much longer than ωp−1, where ωp is electron plasma frequency. A set of coupled nonlinear differential equations is shown to exist in such a scenario. Propagating soliton solutions are demonstrated from these equations.
