论文摘要
原子蒸气细胞中的RABI测量值在一系列微波成像和传感实验中具有目前感兴趣,但是在通过自旋交换碰撞定义的相干性研究之外,越来越多地在参数空间中。在这里,我们通过使用Faraday旋转采用$^{87} $ rb的超精美歧管的连续无损读数来研究蒸气细胞中Rabi振荡的连贯性。我们为超精细转变的自旋交换(SE)连贯性开发了一个完整的模型,该模型考虑了非静态人群分布。在此制度中,Rabi振荡表现出非平凡的时间域信号,允许验证蒸气细胞参数。我们发现理论和实验之间的一致性很高,这将有助于基准基准对Rabi测量应用的敏感性。
Rabi measurements in atomic vapor cells are of current interest in a range of microwave imaging and sensing experiments, but are increasingly in a parameter space outside of theoretical studies of coherence defined by spin-exchange collisions. Here, we study the coherence of Rabi oscillations in vapor cells by employing continuous non-destructive readout of the hyperfine manifold of $^{87}$Rb using Faraday rotation. We develop a full model for spin-exchange (SE) coherence for hyperfine transitions that takes into account a non-static population distribution. In this regime, Rabi oscillations exhibit nontrivial time-domain signals that allow verification of vapor-cell parameters. We find excellent agreement between theory and experiment, which will aid in benchmarking sensitivities of Rabi measurement applications.
