Electron acoustic solitary waves in unmagnetized nonthermal plasmas. (15th March 2021) - Khalid, Muhammad
Abstract: Electron acoustic (EA) solitary waves (SWs) are studied in an unmagnetized plasma consisting of hot electrons (following Cairns-Tsalli distribution), inertial cold electrons, and stationary ions. By employing a reductive perturbation technique (RPT), the nonlinear Korteweg–de Vries (KdV) equation is derived and its SW solution is analyzed. Here, the effects of plasma parameters such as the nonextensivity parameter ( q ), the nonthermality of electrons ( α ), and the cold-to-hot electron density ratio ( β ) are investigated.
