Two typical collective behaviors of the heavy ions expanding in cold plasma with ambient magnetic field

We have numerically studied the evolution of heavy ions that expand in a cold background plasma at large scale. Two typical collective behaviors are identified with conditions where only traversing ions' initial total mass is different. Our work has demonstrated difference moving able to induce completely different plasma. The simulation performed via hybrid model which and electrons treated as classical particles mass-less fluids, respectively. Due imbalance electric magnetic force on ions, these will evolve into patterns eventually. These manifest rather stopping behavior an opposite drifting direction electron fluid rim expanding Further numerical analytical calculations show depends not number densities but also spatial variations fields. reveals highly non-linear, non-linearity phenomena system
