Abstract:
We performed a fluid simulation of the head-on collision of supersolitary waves (SSWs) with regular solitary waves (RSWs) in a plasma
consisting of cold fluid ions and two-temperature electrons having kappa distributions. We have set up the fluid simulation to evolve both ion
acoustic (IA) SSWand IA RSW self-consistently. Our simulation shows that the generated SSW and RSW maintain their shapes while propagating
at a constant speed. Furthermore, the simulation demonstrates that the head-on collision of SSW with RSW does not affect their original
characteristics, revealing their soliton-type behavior. This is the first simulation to confirm the soliton-type behavior of the SSWs in plasma.
