Collisional effects on the electrostatic shock dynamics in thin-foil targets driven by an ultraintense short pulse laser
Andréas Sundström, Laurent Gremillet, Evangelos Siminos +1
We numerically investigate the impact of Coulomb collisions on the ion dynamics in high-, solid density caesium hydride and copper targets, irradiated by high-intensity ($I\appr…
Dynamo in weakly collisional nonmagnetized plasmas impeded by Landau damping of magnetic fields
István Pusztai, James Juno, Axel Brandenburg +4
We perform fully kinetic simulations of flows known to produce dynamo in magnetohydrodynamics (MHD), considering scenarios with low Reynolds number and high magnetic Prandtl number…
Fast collisional electron heating and relaxation in thin foils driven by a circularly polarized ultraintense short-pulse laser
Andréas Sundström, Laurent Gremillet, Evangelos Siminos +1
The creation of well-thermalized, hot and dense plasmas is attractive for warm dense matter studies. We investigate collisionally induced energy absorption of an ultraintense and u…
Effect of a weak ion collisionality on the dynamics of kinetic electrostatic shocks
Andréas Sundström, James Juno, Jason M. TenBarge +1
In strictly collisionless electrostatic shocks, the ion distribution function can develop discontinuities along phase-space separatrices, due to partial reflection of the ion popul…
