Electron beam-plasma interaction in a dusty plasma with excess suprathermal electrons

TL;DR

This paper explores how electron beams influence large-amplitude electron-acoustic solitary waves in a dusty plasma with suprathermal electrons, using a nonlinear pseudopotential approach to analyze their properties and dependencies.

Contribution

It introduces a detailed analysis of electron beam effects on solitary structures in dusty plasmas with suprathermal electrons, expanding understanding of wave behavior in such environments.

Findings

Electron beams significantly affect solitary wave characteristics.

Dust and electron beam parameters influence wave existence and properties.

Stationary solitary waves depend on plasma composition and beam intensity.

Abstract

The existence of large-amplitude electron-acoustic solitary structures is investigated in an unmagnetized and collisionless two-temperature dusty plasma penetrated by an electron beam. A nonlinear pseudopotential technique is used to investigate the occurrence of stationary-profile solitary waves, and their parametric dependence on the electron beam and dust perturbation is discussed.
