PIC simulation and physical interpretation of the formation and evolution of an electrostatic shock in a collisionless plasma produced by a fs laser pulse

摘要

We carry out 1D and 2D PIC-simulation of the formation and evolution of a (quasi)electrostatic shock in a dual-temperature collisionless plasma with parameters typical for the laboratory femtosecond-laser experiments. We consider various profiles of a transition layer between the cold background and hot bulk expanding plasmas and analyzed how their parameters influence the properties and dynamics of the shock.
