Our research is focused on the quantum interaction between light and matter at atomic and nanoscales and related phenomena. Light-matter interaction is the foundation of many important fields, including precision measurements, quantum sensing, quantum communication, quantum computing, optical imaging, thermal radiation, and solar energy.
