A Study on Sagdeev Pseudopotential and Electrostatic Potential of Solitons in Four-Component Magnetized Dusty Plasma

The nonlinear dynamics and its wide range of applications have increased the curiosity of researchers. In short span of time, solitons have become the major interest of physicists. We investigate the nonlinear profile of plasmonic solitons with four components consisting of hot electrons, cold electrons, hot ions, and hot protons. In this framework, a couple of equations of motion are derived by invoking the reductive perturbation technique, and the resultant modified Korteweg—de Vries (m-KdV) equation is solved by the sine cosine method. Here, we analyze the effect of Sagdeev pseudopotential and the electrostatic potential with different system parameters and the characteristics of solitons are found.
