Formation and Interaction of Sonic-Langmuir Solitons: Inverse Scattering Method

Abstract

We consider behaviour of sonic-Langmuir solitons which are Langmuir oscillations trapped in regions of reduced plasma density caused by the ponderomotive force due to a high-frequency field. In particular, the formation and the interaction of solitons are studied by the inverse scattering technique in the case of the Langmuir waves coupled with ionacoustic waves propagating in one-direction.
