laser淬灭对“原子二极管”的改进：超冷原子的单向势垒
Improvement by laser quenching of an "atom diode": a one-way barrier for ultra-cold atoms
摘要：
最近有人提出了不同的激光装置，用作超冷原子的“原子二极管”或"单向势垒“。它们透射来自一侧的基态能级原子，比如说从左边，但是当它们来自另一侧时反射它们。我们结合了以前的模型，由受激拉曼绝热通道（STIRAP）从地面到激发态和一个状态选择镜电位，与本地淬火激光产生自发衰减回基态。这避免了向后运动，提供了对衰变过程的更多控制，因此是更紧凑和有用的装置。
英文摘要：
Different laser devices working as ``atom diodes'' or ``one-way barriers'' for ultra-cold atoms have been proposed recently. They transmit ground state level atoms coming from one side, say from the left, but reflect them when they come from the other side. We combine a previous model, consisting of the stimulated Raman adiabatic passage (STIRAP) from the ground to an excited state and a state-selective mirror potential, with a localized quenching laser which produces spontaneous decay back to the ground state. This avoids backwards motion, provides more control of the decay process and therefore a more compact and useful device.
