Nonlinear Ion Acoustic Wave Excitations in Magnetized Plasma with Cairns Hot and Cold Electron Distribution and Monoenergetic Electron Beam

In this paper the nonlinear impacts of a magnetized plasma having inertialess nonthermal two kinds electrons with Cairns distribution, warm ions, along with monoenergetic beam electron has been investigated. A Korteweg-de Vries (KdV) equation governing this model is derived by employing the reductive perturbation method. Our plasma model supports both positive and negative solitary waves structure.The presence of an electron beam as a unique component significantly influences the propagation of ion acoustic mode in this plasma system. The result indicates that the solitary wave propagation in the plasma model changes the characteristic of solitary waves such as amplitude, phase speed, width, and nonlinear coefficient due to the presence of electron beams. The findings show that the number density of the beam electron can be employed to control the propagation of ion acoustic solitary waves in this model. The present study can contribute to comprehending the nonlinear features of ion acoustics solitary waves in both laboratory and space plasma environments, particularly those involving electron beam and nonthermal particles.
