Understanding the response of quantum matter to changes in the system parameters is crucial in developing new technologies. Recent advances in ultracold atomic gases have enabled the systematic study of the fastest collective response possible in any quantum system (relative to system density). Specifically, the low particle density and large atom mass compared with electrons in solids means that the relevant time scale for quantum dynamics is slowed down from attoseconds to microseconds, by more than 10 orders of magnitude. At the same time, ultracold gases feature unprecedented control of interactions, atom spins, and geometry, allowing the study of a wealth of possible out-of-equilibrium scenarios.
This theoretical project aims to predict the collective response of quantum matter to interferometric techniques originally envisioned for two-level systems using newly developed tools. It will explore which aspects of dynamics stem from the behaviour of few particles, and which are unique to many particle systems.
