Ce travail a comme objectif d'étudier diverses solutions pour la mise en place d'une plate-forme de simulation numérique. Celle-ci doit pouvoir rassembler plusieurs...

The goal of magnetic confinement devices such as tokamaks is to produce energy from nuclear fusion reactions in plasmas at low densities and high temperatures....

A new model of the self-consistent coupling between low frequency, ion-scale coherent magnetic structures and high frequency whistler waves is proposed in order to...

This work is devoted to the study of a problem resulting from plasma physics: heat transfer of electrons in a plasma close to Maxwellian equilibrium. Firstly, the...

Gyrokinetics is a key model for plasma micro-turbulence, commonly used for fusion plasmas or small-scale astrophysical turbulence, for instance. The model still...

The context of the present work is the one of planetary plasma environments. I show how, by analysis of in-situ observations combined to numerical simulations and...
