我们报道了在≈400nk的超冷Rb气体中单个Cs原子的受控插入。这需要将冷却、捕获和操纵单个激光冷却原子所需的技术与产生超冷简并量子气体的实验相结合。在我们的方法中,这两个系统都在单独的陷阱中准备,然后组合。我们的结果为量子气体与其他物种的单个或少数中性原子之间的相干相互作用铺平了道路。
We report on the controlled insertion of individual Cs atoms into an ultracold Rb gas at ≈400 nK. This requires one 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.
