Atomtronics is a relatively new subfield of atomic physics that aims to realize the device behavior of electronic components in ultracold atom-optical systems. The fact that these systems are coherent makes them particularly interesting since, in addition to current, one can impart quantum states onto the current carriers themselves or perhaps perform quantum computational operations on them. After reviewing the fundamental ideas of this subfield, we report on the theoretical and experimental progress made towards developing externally-driven and closed loop devices. The functionality and potential applications for these atom analogs to electronic and spintronic systems is also discussed.

 原子电子学的进展


原子电子学是原子物理学的一个相对较新的子领域，旨在实现超冷原子光学系统中电子元件的器件行为。这些系统具有相干性这一事实使它们特别有趣，因为除了电流之外，人们还可以将量子态传递给电流载流子本身，或者可能对它们执行量子计算操作。在回顾了该子领域的基本思想后，我们报告了开发外部驱动和闭环设备所取得的理论和实验进展。还讨论了这些原子类似物在电子和自旋电子系统中的功能和潜在应用。
