论文摘要
蛀牙光学机械在量子信息处理和基本物理研究中都很重要。在本文中，我们提出了一个光学机械晶格，该晶格表现出非热物理学。我们首先使用非Bloch带理论来研究光力晶格的能量光谱和传输特性。系统的广义布里渊区是在结果的帮助下计算的。随后给出了周期性边界条件（PBC）和开放边界条件能量谱。通过在不同位点引入探针激光器，我们观察到系统的定向扩增。分析扩增的方向与非铁皮皮肤效应相结合。通过考虑PBC能量光谱来分析支持扩增的频率。通过在一个站点上引入探针激光器，我们可以研究现场传输属性。可以在我们的系统中实现光机电诱导的透明度（省略）。通过改变系统的参数和大小，可以有效地调节忽略峰，甚至可以变成光机电诱导的放大。我们的系统显示其潜力是单向信号滤波器的功能。并且我们的模型可以扩展到其他非热骨模型，该模型可能具有拓扑特征和双极非铁皮皮肤效应。
Cavity optomechanics is important in both quantum information processing and basic physics research. In this paper, we propose an optomechanical lattice which manifests non-Hermitian physics . We first use the non-Bloch band theory to investigate the energy spectrum and transmission property of an optomechanical lattice. The generalized Brillouin zone of the system is calculated with the help of the resultant. And the periodical boundary condition (PBC) and open boundary condition energy spectrum are given, subsequently. By introducing probe laser on different sites we observed the directional amplification of the system. The direction of the amplification is analyzed combined with the non-Hermitian skin effect. The frequency that supports the amplification is analyzed by considering the PBC energy spectrum. By introducing probe laser on one site we investigate the onsite transmission property. Optomechanically induced transparency (OMIT) can be achieved in our system. By varying the parameters and size of the system, the OMIT peak can be effectively modulated or even turned into optomechanically induced amplification . Our system shows its potential as the function of a single-way signal filter. And our model can be extended to other non-Hermitian Bosonic model which may possess topological features and bipolar non-Hermitian skin effect.
