Topologically nontrivial electromagnetic states

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.
