Description |
Ultracold atoms have recently emerged as a new platform to study models of strongly interacting many-body systems, which are relevant in various fields from nuclear physics to condensed matter physics, in a controlled environment. In this talk, I will briefly review how cold atoms can shed light on interesting condensed matter systems. The dynamics of these systems close to equilibrium, combined with the unique measurement tools available in this platform, can provide information about many-body correlations, which can be used to identify novel phases in these strongly interacting systems. I will use optical lattice modulation spectroscopy as an example to illustrate this point. Cold atoms also provide an opportunity to study the intrinsic dynamics of strongly interacting quantum systems far from equilibrium, which is not readily available in standard condensed matter systems. In this context, I will present results on non-equilibrium relaxation dynamics of high energy excitations in a Fermi Hubbard model. |
