Research Interests
Our research is in the broad field of light-matter interaction, with an emphasis on many-body physics, quantum optics, nonlinear optics, laser spectroscopy, and cavity quantum electrodynamics in semiconductor nanostructures.
In particular, we are interested in (i) undertanding the many-body interactions and quantum collective phenomena and (ii) developing optical manipulation and coherent control of electron and nuclear spinseffects in low-dimensional nanostructures such as quantum wells, wires and dots. These mesoscopic material systems whose sizes, on the order of nanometers, are intermediate between those of atoms and bulk solids. The quantum size effects dramatically reshape the many-body interactions; therefore, these systems are ideal testbeds for understanding both (a) quantum collective phenomena (eg. quantum Hall effects and Bose-Einstein condensation) and (b) isolated quanta with long coherence time (eg. electron and nuclear spins in quantum dots).
