Interests and Activities:

My research interests are mainly in the new physics discovered in a variety of correlated electron systems ranging from the quantum dots, the low-dimensional magnets and metals, to the HTS cuprates and the heavy Fermion alloys, etc. The recent research problems include the Mott physics, the quantum magnetism, the non-Fermi liquids, the quantum phase transitions, and the quantum criticality in these correlated electron systems.
