Ion acoustic quasi-soliton in an electron-positron-ion plasma with superthermal electrons and positrons

Ion acoustic quasi-soliton in an electron-positron-ion plasma with superthermal electrons and positrons

In this work, we are concerned with the ion acoustic quasi-soliton in an electron-positron-ion plasma with superthermal electrons and positrons. By using the reductive perturbation method, the Korteweg-de Vries equation is derived from the governing equations of ion acoustic waves. An interesting so...
