The advanced quantum mechanics course is given by Dominique Mouhanna and Frédéric Van Wijland.

Dominique Mouhanna’s research stands at the boundary between field theory and condensed matter physics. His main activity is to use nonperturbative renormalization group techniques in order to elucidate the critical, and more generally, the long distance behaviour of systems coming from statistical, condensed matter, and soft matter physics.

Frédéric van Wijland's research works lie at the crossroads of statistical mechanics and field-theoretic methods, with a view to describing the emergent collective behavior of nonequilibrium systems.
