Donald W. Booth, Joshua Isaacs, M. Saffman

摘要:

我们提出了一种方法,用于减少原子地面里德堡跃迁的杂散直流电场的灵敏度,使用微波诱导的里德伯态敷料。计算的Cs $\state{90S}{1/2}$和$\state{90P}{3/2}$状态。在零直流偏置电场的情况下,使用双频交流场来同时降低两种状态对直流场变化的灵敏度。对于$\state{90S}{1/2}$状态,灵敏度降低为95倍,对于$\state{90P}{3/2}, m_J=3/2$状态,灵敏度降低为1600倍。我们还展示了如何的两个频率的交流字段可以用来取消二阶和四阶项的极化率的一个单一的里德堡状态。这些结果是相关的,以提高稳定性的实验,试图激发里德伯原子附近的带电表面。

英文摘要:

We propose a method for reducing the sensitivity of atomic ground to Rydberg transitions to stray dc electric fields, using microwave-induced dressing of Rydberg states. Calculations are presented for the Cs $\state{90S}{1/2}$ and $\state{90P}{3/2}$ states. With zero dc bias electric field, a two-frequency ac field is used to simultaneously reduce the sensitivity of both states to dc field variations. The sensitivity reduction is a factor of 95 for the $\state{90S}{1/2}$ state and a factor of 1600 for the $\state{90P}{3/2}, m_J=3/2$ state. We also show how the two-frequency ac field can be used to cancel both second- and fourth-order terms in the polarizability of a single Rydberg state. These results are relevant to improving the stability of experiments that seek to excite Rydberg atoms in the proximity of charged surfaces.
