Collision of two radial rarefaction waves in unmagnetized ambient plasma: effects of the ambient plasma density
Margaux François, Mark E. Dieckmann, Lorenzo Romagnani +2
The expansion of two circular rarefaction waves in vacuum or in a thin ambient plasma is examined with particle-in-cell simulations that resolve two spatial dimensions. In the simu…
