论文摘要
事实证明，通过频率分辨的光子相关性是公开标准可观察物中隐藏的非线性的有用资源，例如光谱或标准（色盲）光子相关性。在此手稿中，我们分析了从光学机械系统发出的光子的频率分辨相关性，在该系统中，光是非线性耦合与谐振器机械模式的量化运动的，但是通常难以证明量子非线性响应。我们介绍并揭示了频率分辨相关性的丰富景观，并讨论时间延迟的相关性如何揭示有关系统动力学的信息。我们还研究了相关性对相关参数的依赖性，例如单光子耦合强度，滤波线宽或环境中的热噪声。对系统的这种丰富理解可以触发新的实验来探测光学机械中的非线性现象，并提供对通用非线性系统动力学的见解。
Frequency-resolved photon correlations have proven to be a useful resource to unveil nonlinearities hidden in standard observables such as the spectrum or the standard (color-blind) photon correlations. In this manuscript, we analyze the frequency-resolved correlations of the photons being emitted from an optomechanical system where light is nonlinearly coupled to the quantized motion of a mechanical mode of a resonator, but where the quantum nonlinear response is typically hard to evidence. We present and unravel a rich landscape of frequency-resolved correlations, and discuss how the time-delayed correlations can reveal information about the dynamics of the system. We also study the dependence of correlations on relevant parameters such as the single-photon coupling strength, the filtering linewidth, or the thermal noise in the environment. This enriched understanding of the system can trigger new experiments to probe nonlinear phenomena in optomechanics, and provide insights into dynamics of generic nonlinear systems.
