Abstract

Cold atoms represent an ideal platform for the implementation of second-generation quantum technologies. Particularly interesting opportunities emerge from a coherent coupling of the atoms to a single-mode light field enabled by a resonant optical cavity. This project will pursue two research lines. The first one is a study of the interaction of ultracold atoms with a ring cavity in parameter regimes suitable for the creation of non-classical collective states of the atomic cloud with possible application in Heisenberg-limited interferometry. The regime may also allow for a global synchronization of the atomic dipoles with application in superradiant lasing. The second research line is devoted to setting up a high sensitivity matter-wave interferometer for inertial sensing and gravimetry. It is based on observing in real time Bloch oscillations performed by atoms located inside a periodic optical lattice formed by two counter-propagating modes of the cavity and exploits the fact that the periodicity of the oscillations is strictly proportional to external forces.
