The linear Rayleigh-Taylor instability with foams
Antoine Bret, Audrey DeVault, Skylar Dannhoff +3
We analyse the behaviour of the linear phase of the Rayleigh-Taylor instability (RTI) in the presence of a foam. Such a problem may be relevant, for example, to some inertial confi…
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…
On the width of a collisionless shock and the index of the cosmic rays it accelerates
Antoine Bret, Asaf Pe'er
Despite being studied for many years, the structure of collisionless shocks is still not fully determined. Such shocks are known to be accelerators of cosmic rays, which, in turn,…
Density jump for oblique collisionless shocks in pair plasmas: physical solutions
Antoine Bret, Colby C. Haggerty, Ramesh Narayan
Collisionless shocks are frequently analyzed using the magnetohydrodynamics (MHD) formalism, even though MHD assumes a small mean free path. Yet, isotropy of pressure, fruit of bin…
Collisionless shock formation, spontaneous electromagnetic fluctuations and streaming instabilities
A. Bret, A. Stockem, F. Fiuza +4
Collisionless shocks are ubiquitous in astrophysics and in the lab. Recent numerical simulations and experiments have shown how they can arise from the encounter of two collisionle…
