Research Interests and achievement
Updated on September 3, 2006
My research interest is to study the ground state properties as well as the elementary excitations of strongly correlated electronic and/or cold atoms systems. In my Ph. D period, we developed the first complete theory to explain the long-term puzzles observed in the resonant Raman scattering experiment on semiconductor heterostructure. From 2001 to 2002, I changed interest and began to investigate the exotic quantum phases and elementary excitations in multicomponent quantum Hall systems.
From 2002 , I spent most of the time on the strongly correlatedeffects of ultracold atoms. We gave the first complete and experimentally verified theory to explain the fragmentation phenomena of microchip condensate due to surface disorder. We also predicted exotic quantum phase transition between antiferromagnetic order and d-wave superfluidity in Bose-Fermi mixtures (BFM) in 2D optical lattice, and found a strong polaronic effect in 1D BFM system. After coming back to Taiwan, I developed the first full strong coupling theory to explain the fermion pairing superfluidity in the adiabatic regime of a BFM, which is most closely related to experimental situation but not accessible in previous theoretical papers. I also began to study the systems of dipolar molecules, which will be one of the most interesting topics in cold atom field in the future.
