Cooperative scattering from (dis-)ordered ultracold strontium clouds

We are currently setting up an experiment to cool and Bose-condense strontium atomic gases. Our goal is to study the cooperative scattering of light by disordered and periodically ordered atomic clouds and quantum matter organized in three-dimensional optical lattices. Particular attention will be given to the observation of Mie resonances and forbidden photonic bands.

Gravitational quantum sensing with atoms in optical ring cavities

Atomic gravimeters based on matter wave interference are among the most accurate gravity sensors. A technique which is particularly appealing by its conceptual simplicity detects Bloch oscillations of atoms falling through a vertical standing light wave. We started realizing such a gravimeter with Bose-condensed strontium with the additional highlight of in vivo monitoring the oscillatory matter wave trajectory.
