论文摘要
我们提出了一个基于光力机械阵列阵列的稳健且可调的非倒数声子传输的平台。在我们的方法中，使用最先进的几何方法和光力机械相互作用的光子自旋轨道耦合的相互作用破坏了时间反向对称性。我们通过研究其对缺陷的鲁棒性来证明该系统的拓扑保护性质。这种类型的系统可以在基于声子的信息存储和信号处理设备中找到应用程序。
We propose a platform for robust and tunable nonreciprocal phonon transport based on arrays of optomechanical microtoroids. In our approach, time-reversal symmetry is broken by the interplay of photonic spin-orbit coupling, engineered using a state-of-the-art geometrical approach, and the optomechanical interaction. We demonstrate the topologically protected nature of this system by investigating its robustness to imperfections. This type of system could find application in phonon-based information storage and signal processing devices.
