Physique théorique et modélisation

Deux approches sont actuellement poursuivies dans l’équipe: physique quantique mésoscopique et descriptions ab initio des propriétés électroniques des matériaux. Dans le cas de la physique quantique mésoscopique, l’objectif est de saisir les mécanismes physiques sous-jacents d’un phénomène donné, et de fournir des descriptions qualitatives et quantitatives des données expérimentales. Tout d’abord, un modèle approprié et mathématiquement traitable, contenant les ingrédients essentiels, est développé. Ensuite, le modèle est résolu en utilisant des outils analytiques ou numériques. L’autre axe vise à développer de nouvelles méthodes de calcul donnant une description fiable des résultats expérimentaux pour la structure électronique et le transport dépendant du spin des matériaux à hétérojonction, consacrées aux technologies de l’électronique de spin. Cette étude est effectuée au moyen de la théorie fonctionnelle de densité (DFT) dépendante du spin.
