Interacting Cold Rydberg Atoms: a Toy Many-Body
... Techniques for laser cooling and trapping of neutral atoms by laser light were developed in the 80’s and 90’s. It was in particular demonstrated that atomic samples could be cooled down to temperatures below 100 µK starting from vapors at room temperature. The basic mechanism that makes laser coolin ...

Addressing of individual atoms in an optical dipole trap
... Josephson junctions [Mak01] and cavity quantum electrodynamics. Each of these approaches has its own advantages and disadvantages. Our approach is to use neutral atoms as carriers of quantum information, which is encoded in their long-living hyperfine ground states. The main advantage of neutral ato ...

Optical pumping of a lithium atomic beam for atom interferometry
... I0 = P/(πw02 ) and, in the calculations, we use the same power P = 5 mW for the two laser beams. Initially, the atomic population is equally distributed among the 8 ground state sublevels. Figure 2 plot the populations of the sublevels of the ground state as a function of time t. In this ideal case, ...
