Topological properties play a fundamental role in many physical phenomena. The best known examples are quantum Hall systems, where insensitivity to local properties manifests itself as conductance through edge states that is insensitive to disorder. While the traditional research focus has been on electronic systems, there has been a recent emergence of great interest in exploring topological orders with photons. Several novel intriguing theoretical schemes have been proposed to explore topological orders in photonic systems, both in the linear and strongly interacting regimes. This project aims to develop innovative theoretical and experimental approaches to explore topologically non-trivial states, from microwaves to optical regimes.

拓扑性质在许多物理现象中起着重要的作用。最著名的例子是量子霍尔系统，其中对局部性质的不敏感性表现为通过对无序不敏感的边缘状态的电导。虽然传统的研究重点一直是电子系统，最近出现了极大的兴趣，探索与光子的拓扑秩序。人们提出了一些新颖的理论方案来研究光子系统中的拓扑序，包括线性和强相互作用两种情况。该项目旨在开发创新的理论和实验方法来探索从微波到光学状态的拓扑非平凡状态。
