论文摘要
我们计算了从线性化量子波动理论的吸收性光学双重性的弱兴奋性限制中，稳态和一阶时间变化的原子场相关函数。在[H. J. Carmichael，物理。 Rev. A 33，3262（1986）]，适用于确定互相关的，因为它不诉诸绝热消除。特别重点是从消失的光子损失速率获得的集体强耦合的极限。我们将腔传递光谱与宏观耗散系统获得的实验结果进行比较，讨论了作为独特的非经典特征引起的异常相关性的作用。
We calculate the steady-state and first-order time varying atom-field correlation functions in the weak-excitation limit of absorptive optical bistability from a linearized theory of quantum fluctuations. We formulate a Fokker-Planck equation in the positive P representation following the phase-space analysis of [H. J. Carmichael, Phys. Rev. A 33, 3262 (1986)] which is suitable for the determination of cross-correlations as it does not resort to adiabatic elimination. Special emphasis is placed on the limit of collective strong coupling as attained from a vanishing photon-loss rate. We compare to the cavity-transmission spectrum with reference to experimental results obtained for macroscopic dissipative systems, discussing the role of anomalous correlations arising as distinct nonclassical features.
