The phase shift in the collision of solitary waves with different angles in 2D unmagnetized quantum plasma

We study the interplay of two ion-acoustic solitary waves (IASWs) with in a 2D hot ion plasma by using the method of the extended Poincaré-Lighthill-Kuo (PLK) perturbation, and obtain two Korteweg-de Vries (KdV) equations describing two solitary waves travling with the different directions. We demon...

Summary:We study the interplay of two ion-acoustic solitary waves (IASWs) with in a 2D hot ion plasma by using the method of the extended Poincaré-Lighthill-Kuo (PLK) perturbation, and obtain two Korteweg-de Vries (KdV) equations describing two solitary waves travling with the different directions. We demonstrate that the phase shifts and trajectories in the head-on collision of two solitary waves with different impingement angles. The results suggest that the plasma parameters can affect deeply the phase shifts in the collision of the solitary waves.
