讲座内容:

Microcavity polaritons are partial-light partial-matter quasi-particles, originating from the strong coupling of excitons (electron-hole pairs) and photons in (planar) microcavities. The hybrid nature gives rise to a strong polariton-polariton interaction, which is one of the main factors for the realization of non-equilibrium polariton condensation. Polariton condensates show rich nonlinear phenomena and topological properties. Especially, the interplay ofthe nonlinearity and topology in polariton systems can leads to novel physical properties. In this talk, several fascinating nonlinear and topological phenomena that recently have attracted significant attention in both physicsand chemistry will be reviewed.
