Bridging the Gap between Collisional and Collisionless Plasma Shocks: A Simulation Study using OSIRIS
Yossef Nissim Kindi, Asaf Pe'er, Antoine Bret +2
Shock waves in plasmas can be characterized by the mechanisms behind their formation. When binary collisions are frequent, dissipation is collision-driven and the shock width is a…
Density jump as a function of the field for parallel relativistic collisionless shocks
Antoine Bret, Ramesh Narayan
Collisionless shocks are frequently analyzed using the magnetohydrodynamic formalism (MHD), even though the required collisionality hypothesis is not fulfilled. In a previous work…
The Vlasov equation cannot fully account for collisionless shocks
Antoine Bret
It is argued that the Vlasov equation cannot fully account for collisionless shocks since it conserves entropy, while a shock does not. A rigorous mathematical theory of collisionl…
A mechanism that could stop the acceleration process within a collisionless shock
Antoine Bret, Asaf Pe'er
Collisionless shocks are complex nonlinear structures that are not yet fully understood. In particular, the interaction between these shocks and the particles they accelerate remai…
