Rydberg atoms open new perspectives for long-range correlated many-body states due to their strong van der Waals interactions.
In one experiment, we investigate Rydberg gases in the fully dipole blockaded regime and observe coherent collective Rabi oscillations for ensembles from a single up to 180 atoms. We optically excite the Rydberg atoms and detect them with submicron resolution, allowing to gain information about the local structure of the prepared states, especially where the fully-blockaded assumption breaks down.
In a second experiment, we implemented single-photon excitation to rubidium Rydberg P-states via an ultra-violet transition at 297 nm. We report on the observation of correlated loss due to the P-state Rydberg-Rydberg interactions and first experiments on Rydberg dressing potentials.
