论文摘要
我们表明，在弱驱动的Jaynes-Cummings（JC）模型的强耦合极限中，多光子过渡的饱和度伴随着量子多模式的逐渐崩溃。通过一种扰动方法，我们通过在稳态平均光子数量低于或略高于统一性的状态下，将量子波动的显着作用说明了量子波动的重要作用。我们还揭示了向前散射光子的强度相关函数中的两个共存的量子beats。这些节拍起源于介导级联衰变的状态，是独特的JC频谱的直接结果。它们的干扰与Wigner函数的正相值围绕相位的瞬态函数的正值和负值的交替进行了坐标。
We show that the saturation of a multiphoton transition is accompanied by a gradual collapse of quantum multimodality in the strong-coupling limit of the weakly driven Jaynes-Cummings (JC) model. By means of a perturbative method, we illustrate the prominent role of quantum fluctuations by focusing on the two and three-photon resonance operation in a regime where the steady-state average photon number is below or marginally above unity. We also reveal two coexistent quantum beats in the intensity correlation function of the forwards scattered photons. These beats, originating from the states mediating the cascaded decay, arise as a direct consequence of the distinct JC spectrum. Their interference coordinates with the alternation of positive and negative values of the Wigner function around the phase-space origin in the transient conditioned on a photodetection.
