Many-body Dynamics

The advent of unprecedented control and a high degree of isolation from the environment in ultracold atoms enable the experimental observations of interesting quantum dynamics in few to many interacting particles. Motivated by these advances, we investigate the dynamics of many-body systems, with a special focus on cold atoms, resulting from a quench or a change in one of the system parameters. We combine analytical and numerical techniques to study various dynamical phenomena in many-body systems.
