Soliton solutions of coupled inhomogeneous nonlinear Schrodinger equation in plasma

Abstract

We consider the coupled system of inhomogeneous damped nonlinear Schrodinger equation which explains wave propagation in plasma. We generalise the (2 x 2) Ablowitz, Kaup, Newell and Segur(AKNS) formalism and construct the linear eigenvalue problem of coupled system. We use the Bdcklund transformation method to derive explicit form of one-soliton solution. (c) 2005 Published by Elsevier Ltd.
