Recent experimental advances in the field of cavity optomechanics have led to the exciting possibility of realizing optomechanical arrays. In this project, we intend to explore novel topological phases in multimode optomechanical settings. In particular, we will focus on the situation where dissipation induces a non-trivial band topology. We will investigate directional (non-reciprocal) optical and mechanical edge-state amplification, as well as the impact of topology on quantum resources, such as multimode entanglement.

腔光机械领域的最新实验进展使实现光机械阵列成为可能。在这个项目中，我们打算在多模光机械环境中探索新的拓扑相。特别是，我们将重点讨论耗散导致非平凡带拓扑的情况。我们将研究定向(非互易)光学和机械边态放大，以及拓扑对量子资源的影响，如多模纠缠。
