Research Interest

  There are two main directions in my current research; one is to generate ultracold molecules and study their many-body interactions and the other is to utilize ultracold atomic samples to study the low-light-level nonlinear optics and their applications in quantum information science. For the molecule research, we are developing a combined approach with the helium buffer gas cooling and direct laser cooling to generate ultracold SrF molecules. The subsequent study will be on the dipolar interaction between ultracold molecules which may limit the lifetime and final temperature of the sample. For the atom research, we utilize the electromagnetically-induced transparency in optical dense, ultracold cesium atoms to implement the low-light-level nonlinear optics.  We have successfully demonstrated the double slow light scheme to enhance the photon-photon nonlinearity. The current effort is to push of the nonlinearity to few-photon and even single-photon level which has important applications in quantum information science.
