Head-On Collision of Electron-Acoustic Solitons in a Magnetized Plasma

M. Yahia S. El-Labany R. Sabry W. Moslem E. A. Elghmaz

Abstrak

The dynamics of electron-acoustic waves (EAWs) profile and its quasi-elastic head-on collision (i.e., it causes shifts of the postcollision soliton trajectories only) is investigated in a plasma consisting of cold magnetized electrons, background hot electrons obeying nonthermal distribution, and stationary ions. Applying an extended Poincare–Lighthill–Kuo perturbation method, the coupled Korteweg–de Vries equations are derived and solved analytically. The effects of the nonthermal parameter, the angle between the magnetic field direction with the collision line, hot-to-cold electrons number density ratio, hot-to-cold electrons temperature ratio, and electron cyclotron frequency on both the solitary EAW profile and the two solitons collision are investigated. The present model is applied to the plasma in the Earth auroral zone.
