我们观察到了圆形里德堡原子在真空中以及存储在高 Q 腔中的小相干场中的拉比振荡。该信号在与连续整数的平方根成比例的频率处表现出离散傅立叶分量。这提供了腔内场量化的直接证据。傅立叶分量的权重产生场中的光子数分布。对原子腔系统激发能级的研究揭示了极低场强下的非线性量子特征。
We have observed the Rabi oscillation of circular Rydberg atoms in the vacuum and in small coherent fields stored in a high Q cavity. The signal exhibits discrete Fourier components at frequencies proportional to the square root of successive integers. This provides direct evidence of field quantization in the cavity. The weights of the Fourier components yield the photon number distribution in the field. This investigation of the excited levels of the atom-cavity system reveals nonlinear quantum features at extremely low field strengths.
