Abstract: Cylindrical and spherical modified Korteweg-de Vries equations are derived for ion-acoustic solitary waves (IASWs) in an unmagnetized, collisionless electron-positron-ion plasma consisting ...

Nonlinear low-frequency ion acoustic (IA) wave and pair plasma convective cell (PPCC) mode are investigated in pair-ion (PI) plasmas with and without electrons in the presence of sheared flows. IA ...

Fusion reactor needs to operate at very high temperatures and high enough densities of fuel to achieve its goal, produce energy. So, how can you predict the temperature and density profiles of a ...
