论文摘要
超低量子气体是针对地球观察，相对论的地理位置和基本物理定律的测试以及研究多体物理学扩展自由跌落的新现象的理想来源。通过在国际空间站上使用冷原子实验室进行实验，我们对单个Bose-Einstein冷凝水的量子状态获得了精致的控制，为未来的高精度测量铺平了道路。特别是，我们采用快速传输方案，以毫米光度计的精度在毫米距离上穿越原子云，然后使用Matterwwave镜头技术将总膨胀能量大幅度降低至100 pk以下。
Ultracold quantum gases are ideal sources for high-precision space-borne sensing as proposed for Earth observation, relativistic geodesy and tests of fundamental physical laws as well as for studying new phenomena in many-body physics extended free fall. By performing experiments with the Cold Atom Lab aboard the International Space Station, we have achieved exquisite control over the quantum state of single Bose-Einstein condensates paving the way for future high-precision measurements. In particular, we have applied fast transport protocols to shuttle the atomic cloud over a millimeter distance with sub-micrometer accuracy and subsequently drastically reduced the total expansion energy to below 100 pK with matterwave lensing techniques.
