Arbitrary amplitude electron-acoustic solitary waves in magnetoplasma with Kaniadakis distributed electrons

Abstract

This study investigates the arbitrary amplitude high-frequency electron-acoustic (EA) solitary waves (EASWs) in a multi-component magnetoplasma consisting of inertial fluid cold electrons and inertialess Kaniadakis distributed hot electrons and stationary positive ions. The Sagdeev potential approach is implemented to derive the energy-balance equation governing arbitrary amplitude EASWs’ dynamics. On examining the condition responsible for determining the polarity of the waves, it was discovered that the existing model exclusively allows for the existence of negative (rarefactive) EASWs. The influence of critical factors, such as Mach number, the direction of propagation, the strength of the magnetic field, and the κ-deformed parameter on the profile of the EASWs is examined and discussed. We will also determine whether shock waves can exist and propagate in this model or not after checking all the criteria for their existence.
