Our research group explores the frontiers of light-matter interactions, where novel atomic and molecular matters are prepared in the quantum regime and light fields including both continuous wave and ulrashort pulses are exquisitely controlled. The experimental effort builds on and further advances precision measurement, ultracold atoms and molecules, quantum metrology, and ultrafast science and quantum control. We develop new technologies in the areas of high precision laser spectroscopy, atomic and molecular cooling and trapping, optical frequency metrology, quantum control, and ultrafast lasers; and apply these new technologies for research in fundamental physics.
