标题： Transmission of ultracold atoms through a micromaser: detuning effects

摘要： 超冷原子通过微波谐振腔的传输概率在存在腔模与原子跃迁频率之间失谐的一般情况下进行研究。 我们在共振情况下（零失谐）之前建立的结果基础上，推广了 mesa 模式函数。 特别是，展示了通过在腔内使用非共振场，可以非常容易地调节和增强通过微波谐振腔的冷原子的速度选择。 此外，传输概率相对于失谐表现出非常尖锐的共振，这些共振可能为高精度计量目的（原子钟）定义单个腔器件。 显示英文摘要

摘要： The transmission probability of ultracold atoms through a micromaser is studied in the general case where a detuning between the cavity mode and the atomic transition frequencies is present. We generalize previous results established in the resonant case (zero detuning) for the mesa mode function. In particular, it is shown that the velocity selection of cold atoms passing through the micromaser can be very easily tuned and enhanced using a non-resonant field inside the cavity. Also, the transmission probability exhibits with respect to the detuning very sharp resonances that could define single cavity devices for high accuracy metrology purposes (atomic clocks).
