Les travaux de recherche de l’équipe Q-Dyno portent sur la modélisation et la simulation de systèmes nanométriques composés de nombreux constituants en interaction. Nous étudions la dynamique quantique non linéaire des charges et des spins dans différents types de nano-objets : films minces et nanoparticules métalliques, fullerènes, matériaux magnétiques. Nous avons développé plusieurs outils analytiques et numériques, allant de la description complète à N-corps pour les systèmes à quelques électrons, jusqu’aux modèles de champ moyen (Hartree-Fock, TD-DFT) et les descriptions hydrodynamiques. En particulier, notre équipe est spécialiste de la dynamique des systèmes quantiques dans l’espace des phases, basée sur la théorie des fonctions de Wigner.
Notre équipe est aussi impliquée dans la collaboration internationale GBAR basée au CERN, qui étudie l’effet de a gravité sur l’antimatière.
