Transporting, splitting and merging of atomic ensembles in a chip trap
摘要：
提出了一个利用原子芯片产生的含时磁场操纵冷原子的工具箱。线布局，详细的实验过程和结果，提出了以下实验：使用磁传送带定位冷原子和玻色-爱因斯坦凝聚体的分辨率为2纳米;分裂的热云和BEC在可调磁双阱势;控制分裂的冷水库。实现这些操作的设备可以彼此组合。我们证明了这一点，结合水库分裂器和传送带，以获得冷原子分配器。讨论了这些器件在片上量子信息处理、原子干涉测量和约瑟夫森结物理中的重要性。对于所有器械，提供了吸收图像视频序列，以证明其随时间变化的行为。
英文摘要：
We present a toolbox for cold atom manipulation with time-dependent magnetic fields generated by an atom chip. Wire layouts, detailed experimental procedures and results are presented for the following experiments: Use of a magnetic conveyor belt for positioning of cold atoms and Bose-Einstein condensates with a resolution of two nanometers; splitting of thermal clouds and BECs in adjustable magnetic double well potentials; controlled splitting of a cold reservoir. The devices that enable these manipulations can be combined with each other. We demonstrate this by combining reservoir splitter and conveyor belt to obtain a cold atom dispenser. We discuss the importance of these devices for quantum information processing, atom interferometry and Josephson junction physics on the chip. For all devices, absorption-image video sequences are provided to demonstrate their time-dependent behaviour.
