本文报道了一种基于超冷Feshbach分子内态结构的时域“Stückelberg干涉仪”的实现。随后的两个通道，通过一个弱的避免两个不同的轨道角动量状态之间的交叉结合一个可变的保持时间导致高对比度的人口振荡。这允许精确确定两种分子状态之间的能量差。我们展示了高度的控制干涉仪的动态。干涉测量方案为超冷分子的精确测量提供了新的可能性。
We report on the realization of a time-domain "Stückelberg interferometer", which is based on the internal-state structure of ultracold Feshbach molecules. Two subsequent passages through a weak avoided crossing between two different orbital angular momentum states in combination with a variable hold time lead to high-contrast population oscillations. This allows for a precise determination of the energy difference between the two molecular states. We demonstrate a high degree of control over the interferometer dynamics. The interferometric scheme provides new possibilities for precision measurements with ultracold molecules.
