Abstract： Exciton-polaritons are quasiparticles formed by excitons and photons when they are in the strong coupling regime. The hybrid properties inherited from both excitons and photons make it a great platform to study topological photonics. In this talk, I will first talk about recent developments of topological effect in exciton-polaritons such as SSH model and polariton Chern insulator. Then I will present our recent works on polariton antichiral edge states and non-Hermitian skin effect.
