Electron acoustic solitons

Electron acoustic solitons in collisionless and weakly relativistic plasmas are studied. The Krylov-Bogoliubov-Mitropolsky perturbative technique is employed to obtain the nonlinear Schrodinger wave equation. We have numerically investigated modulational instability for different values of the streaming velocity. Graphs have been plotted to see the change in amplitude and inverse width by varying different plasma parameters.
