A fluid simulation-based evidence of the soliton-type behavior of supersolitary waves in plasma

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) SSW and I...

Zusammenfassung: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) SSW and 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.
