Mikołaj K. Schmidt, Ruben Esteban, Geza Giedke, Javier Aizpurua, Alejandro González-Tudela

摘要:

频率分辨的光子相关性已被证明是一个有用的资源,以揭示隐藏在标准的可观测量,如光谱或标准(色盲)光子相关性的非线性。在这篇手稿中,我们分析了从光机械系统发射的光子的频率分辨相关性,其中光与谐振器的机械模式的量化运动非线性耦合,但量子非线性响应通常很难证明。我们提出并揭示了丰富的景观的频率分辨相关性,并讨论如何时间延迟的相关性可以揭示系统的动力学信息。我们还研究了相关性对相关参数的依赖性,如单光子耦合强度,滤波线宽,或在环境中的热噪声。这丰富了对系统的理解,可以引发新的实验来探索光力学中的非线性现象,并提供对一般非线性系统动力学的见解。

英文摘要:

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.
