Inserting single Cs atoms into an ultracold Rb gas
We report on the controlled insertion of individual Cs atoms into an
ultracold Rb gas at about 400 nK. This requires to combine the techniques
necessary for cooling, trapping and manipulating single laser cooled atoms
around the Doppler temperature with an experiment to produce ultracold
degenerate quantum gases. In our approach, both systems are prepared in
separated traps and then combined. Our results pave the way for coherent
interaction between a quantum gas and a single or few neutral atoms of another
species
