The group conducts theoretical research on correlated quantum systems. Our main efforts focus on the physics of systems that constitute promising plateforms for concrete realization of quantum technologies. Together with other systems in condensed matter and quantum optics, ultracold atoms have already produced milestone results, which turn quantum technologies from dream to reality.

In the recent years, quantum simulation has established itself at the interface of experiments and theory. Hence most of the recent dramatic advances on quantum simulations own much to parallel experimental and theoretical developments. In the group, we work along three main lines:
   Propose new protocoles for quantum simulation;
   Elaborate relevant models to interprete and understand simulation results;
   Develop new theoretical approaches for correlated quantum systems.

In this view, we develop both analytical approaches (field theories, mean field approximation, bosonization, ...) and numerical techniques (nonlinear Schrödinger equation, path integral quantum Monte Carlo, variational Monte Carlo, exact diagonalization, static and dynamics DMRG, ...). The main part of our work is purely theoretical but we also have long-term collaborations with experimental groups.
