Theoretical Nuclear Physics and Mathematical Physics

Person in charge of the Unit : Oui

The activities of our group are mainly focused in three directions: nuclear, atomic and molecular spectroscopy, nuclear reactions, and mathematical methods in physics. In nuclear spectroscopy, the methods used are essentially microscopic cluster models for light nuclei. An important part of our research concerns exotic nuclei, and halo nuclei. We also address applications in the atomic or molecular framework of the N body problem. Our activities in the field of nuclear reactions cover different topics, such as reactions of astrophysical interest, and breakup reactions. We also provide theoretical support to different experimental groups.
Mathematical methods in non-relativistic and relativistic quantum mechanics concern the application in microscopic physics of group theory and Lie algebras. They also concern the use of supersymmetry in the inverse problem of collisions.  In addition, we develop numerical methods for the study of quantum N-body systems.  One aspect of our research also concerns the links between classical mechanics and quantum mechanics.
