Research Avtivities
My research activity is devoted to the theory of correlated quantum systems, more precisely on ultracold atoms and quantum simulators. I have first been studying the nonlinear dynamics of cold atoms in dissipative optical lattices and its applications to out-of-equilibrium statistical physics, incuding Brownian diffusion, stochastic resonance, and molecular ratchets (2000-2004). I then turned to the study of the effects of disorder in quantum systems, including localization in quasi-periodic systems, spin glasses, and random-field-induced order (2003-2008). A significant part of my work has been devoted to Anderson localization of matter waves in correlated disordered potentials (2005-2012) as well as to the interplay of disorder and interactions in correlated quantum systems and many-body localization (2007-2015). My research activities now focus on quantum phase transitions (including the Mott and Bose glass transitions) and out-of-equilibrium dynamics of strongly-correlated quantum systems (2013-...). Generally, my work use analytical as well as numerical developments and a part is performed in collaboration with experiments on ultracold atoms.
