The coherent coupling between metallic surface plasmon and exciton in low-dimensional semiconductor induces many new physical phenomena and effects. In this project, we will study the manipulation of optical properties in micro- and nano-structures by plasmon-exciton interaction. We will focus on the strong plasmon-exciton coupling and the resonant energy transfer in the coupled nanosystem, including Rabi oscillation and Fano resonance, quantum plasmon, plasmon in topological insulator and the interaction between plasmon and topological materials, manipulating photon/electron/phonon via plasmon interaction, and enhancing the photocurrent and photocatalytic activity via plasmon resonant energy transfer. The research in this project will be important for the light-matter interaction and the applications in quantum information, chemistry, biomedicine, material, etc.
