Our research group explores the frontier of light-matter interactions. Precisely controlled lasers enable our communications with microscopically engineered quantum systems of atoms and molecules. By preparing matter in specific quantum states, and using probe light with the longest coherence time and precisely controlled waveform, we strive to make fundamental scientific discoveries and develop new enabling technologies.
The strongly integrated development of scientific vision and experimental tools has enabled us to advance important topics in precision measurement, quantum many-body physics, quantum metrology, ultrafast science, and quantum science in general. For example, we employ quantum gas of strontium atoms confined in optical lattices to achieve best performing atomic clocks and investigate novel quantum dynamics, combining quantum metrology and quantum simulation. We prepare molecules in quantum degenerate gases to engineer tunable Hamiltonians for correlated quantum phenomena. These quantum-state prepared molecules are also explored for test of fundamental physics and study of quantum chemistry. Stable lasers and optical frequency combs are extending precision spectroscopy and extreme nonlinear optics from mid infrared to extreme ultraviolet, providing novel probes of large quantum systems, trace detection for health and environment, and new spectroscopy opportunities in a nuclear transition.
