论文摘要
操纵超速混合物的个体成分的技术是研究杂质物理学的关键。在这项工作中，我们将RB-87的超细基态的混合物限制在双孔电势中。电势是通过将原子带有多种射频的化合物产生的。敷料场的每个频率分量的幅度和相位单独控制以独立操纵每个物种。此外，我们验证了我们的超细状态的混合物碰撞稳定，没有可观察到的非弹性损失。
Techniques to manipulate the individual constituents of an ultracold mixture are key to investigating impurity physics. In this work, we confine a mixture of the hyperfine ground states of Rb-87 in a double-well potential. The potential is produced by dressing the atoms with multiple radiofrequencies. The amplitude and phase of each frequency component of the dressing field are individually controlled to independently manipulate each species. Furthermore, we verify that our mixture of hyperfine states is collisionally stable, with no observable inelastic loss.
