玻色-爱因斯坦凝聚体的脉冲抽运
Pulsed pumping of a Bose-Einstein condensate
摘要：
在这项工作中，我们研究了原子相干转移到玻色-爱因斯坦凝聚体的系统。我们利用两个空间分离的玻色-爱因斯坦凝聚体，在不同的超精细基态保持在同一直流磁阱。通过原子的脉冲转移，我们能够在转移的时间上显示出清晰的共振，无论是在温度还是数量上，从中我们可以得出关于潜在物理过程的结论。结果进行了讨论的背景下，最近展示的泵浦原子激光器。
英文摘要：
In this work, we examine a system for coherent transfer of atoms into a Bose-Einstein condensate. We utilize two spatially separate Bose-Einstein condensates in different hyperfine ground states held in the same dc magnetic trap. By means of a pulsed transfer of atoms, we are able to show a clear resonance in the timing of the transfer, both in temperature and number, from which we draw conclusions about the underlying physical process. The results are discussed in the context of the recently demonstrated pumped atom laser.
