Research Interests:
1. Quantum properties of low-dimensional Fermi gas: Studying the exotic quantum phases due to the fermion species, pairing, the external potential, and the interaction;
2. Density functional theory of low-dimensioanl system;
Homogeneous low-dimensional systems are strictly solvable in many cases (eg using the Bethe-Ansatz technique, Bosonization, etc.), and for the inhomogeneous systems they are more complicated and can often be solved by using density functional theory. We study the applications of the density functional theory in the model system. Related examples can be found in the application of density functional theory in the inhomogeneous Hubbard model, non-uniform Lieb-Wu model, Anderson model and Bose-Fermi mixed system. The same idea can be used to deal with disordered problems, finite temperature effects, various dynamical problems;
3. Numerical study of low-dimensional strong correlation system: By means of strict diagonalization and numerical renormalization group, we discuss the ground state, especially the correlation function of low-dimensional systems;
4. Excitation properties of low-dimensional strongly correlation systems: studying low energy excitation such as spin-charge separation phenomenon, spin-drag effect due to the relative motion of different types of fermions, and the use of variational methods and local density approximation to solve the finite temperature, low energy excitation mode.
For students:
I am currently tutoring several graduate students for scientific research. At the same time, I am organizing and supervising a number of junior undergraduates for research and develop their research interests.
