论文摘要
为了研究嵌入在记忆环境中的量子系统的动力学行为，获得储层光谱密度的知识至关重要。但是，这种知识通常基于对环境的先验假设。在本文中，我们提出了一种方法，以获取有关光学谐振器的储层光谱密度的关键信息，而没有关于光谱形状的其他假设。这是通过检测和分析发射光的光传递速率来实现的。在弱的光力单晶耦合方面，我们在输出光谱与储层光谱密度之间建立了一个简单的关系。这提供了一种直接有效的方法，用于重建单个甚至多个脱干通道中的光谱密度曲线。
To investigate the dynamical behavior of a quantum system embedded in a memory environment, it is crucial to obtain the knowledge of the reservoir spectral density. However, such knowledge is usually based on a priori assumptions about the environment. In this paper, we put forward a method to obtain key information about the reservoir spectral density of an optomechanical resonator without additional assumptions about the spectral shape. This is achieved by detecting and analysing the optical transmission rate of the emitted light. In the weak optomechanical singlephoton coupling regime, we establish a simple relation between the output light spectrum and the reservoir spectral density. This provide a straightforward and effective way for reconstructing the spectral density profile in single or even multiple decoherence channels.
