Self-consistent modelling of hot plasmas within non-extensive Tsallis' thermostatistics

A study of the effects of non-extensivity on the modelling of atomic physics in hot dense plasmas is proposed within Tsallis' statistics. The electronic structure of the plasma is calculated through an average-atom model based on the minimization of the non-extensive free energy.Comment: submitted to "Eur. Phys. J. D

Mesoscopic simulations of laser-plasma interaction

We present millimeter-scale numerical studies we have performed about laser-plasma interaction. We have developed for that purpose a specific software, which we call $H\!\rho\alpha$ (Héra) and that we use for studying filamentation, Brillouin and Raman instabilities. We assume the paraxial wave propagation and bitemperature quasi-neutral fluid approximations. A brief description of the main models within $H\!\rho\alpha$, as well as some computation results, will be presented
