  1. Cooperativity and Control in Highly Excited Rydberg Ensembles – Achievements of the European Marie Curie ITN COHERENCE


We present an experimental setup for creating arbitrary two-dimensional arrays of optical microtraps to trap single atoms for experiments with Rydberg atoms. We use a spatial light modulator to manipulate the spatial phase of a far red-detuned optical dipole trap beam, which allows us to create arbitrary arrays of optical microtraps, by focusing the beam with an in-vacuum high numerical-aperture aspheric lens. We load atoms in the microtraps from a dilute cloud of cold atoms, having at most one atom in each trap due to fast light-assisted collisions. Real-time analysis of the atomic fluorescence with a sensitive CCD camera allows us to determine the filling of each trap individually with a  >10 Hz rate. We can create strong interactions between the atoms by exciting them to Rydberg states, with an efficiency of single atom resolved Rydberg detection of  >95%.
