论文摘要
我们确定集体原子自由度在吸收性光学双重性方面的不连贯光谱，挤压特性和二阶相关功能。这是通过在正p表示中的线性化fokker-planck方程来完成的，并由[H. J. Carmichael，物理。 Rev. A 33，3262（1986）]不诉诸绝热消除。我们专注于虚弱和强大的腔内激发的制度，解决了备受障碍和不良腔的限制以及集体强耦合的极限。辅助谐振器与集合的辅助谐振器维持的全绝热场内场被用于通过形成集体发射通道来探测原子相关性。我们将与实验结果相比，与前向散射光的相应表达式进行了比较，讨论了稳态半经典双曲线的下部和上部分支之间的关键差异。我们的分析是在远离转折点的稳定状态周围进行的，在这些状态下，可以自一视的分析表达式获得分析表达式，这表明与经典行为明显不同。
We determine the incoherent spectrum, squeezing properties and second-order correlation function of the collective atomic degrees of freedom in absorptive optical bistability. This is accomplished via a linearized Fokker-Planck equation in the positive P representation, guided by the analysis of [H. J. Carmichael, Phys. Rev. A 33, 3262 (1986)] which does not resort to adiabatic elimination. We focus on the regimes of weak and strong intracavity excitation, addressing the good-cavity and bad-cavity limits as well as the limit of collective strong coupling. Adiabatic elimination of the intracavity field sustained by an auxiliary resonator coupled to the ensemble is used to probe the atomic correlations via the formation of a collective emission channel. We compare to the corresponding expressions for the forwards-scattered light with reference to experimental results, discussing key differences between the lower and upper branch of the steady-state semiclassical bistability curve. Our analysis is carried out around the stable states situated far away from the turning points, where analytical expressions can be obtained self-consistently, demonstrating a clear departure from classical behavior.
