Abstract : 通过有限差分的方法，数值计算了一个相对论性质的Dirac电子在磁场和无序同时存在时的能谱结构，并讨论了不同磁场强度和无序强度时电子密度分布的变化情况．结果发现：随着无序强度的增大，无序势削弱了磁场对电子的捕获，使局域化现象减弱，使得无质量Dirac电子出现了有别于Anderson局域化的现象．

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.
