论文摘要
我们证明了在透明膜中的亚毫米直径孔中产生的冷原子集合，这是一种所谓的“膜MOT”。通过子多普勒冷却过程，被膜MOT捕获的原子被冷却至10英国。未桥接/桥接的膜孔内的原子数约为10^4至10^5，对于400 UM直径的膜孔，MOT云的1/E^2直径约为180 UM。这样的膜装置原则上可以有效地将冷原子加载到悬浮的膜波导产生的evanescent-field光学陷阱中，以实现强大的原子相互作用，并在波导处提供足够的热量散热能力。这代表了朝着光子原子陷阱积分平台（ATIP）迈出的关键步骤。
We demonstrate the generation of a cold-atom ensemble within a sub-millimeter diameter hole in a transparent membrane, a so-called "membrane MOT". With a sub-Doppler cooling process, the atoms trapped by the membrane MOT are cooled down to 10 uK. The atom number inside the unbridged/bridged membrane hole is about 10^4 to 10^5, and the 1/e^2-diameter of the MOT cloud is about 180 um for a 400 um-diameter membrane hole. Such a membrane device can, in principle, efficiently load cold atoms into the evanescent-field optical trap generated by the suspended membrane waveguide for strong atom-light interaction and provide the capability of sufficient heat dissipation at the waveguide. This represents a key step toward the photonic atom trap integrated platform (ATIP).
