Welcome to My homepage!
I am now a PhD candidate in Institute for Advanced Study, Tsinghua University, Beijing,
China. I am currently doing broad research in strong-correlated condensed matter theory in
Prof. Zheng-Yu Weng's group.
NEW UPDATED: I will move to Perimeter Institute for Theoretical Physics to be an Institute
Postdoctoral Fellow starting from September, 2012.

SCIENTIFIC RESEARCH
I show interests in strongly correlated electron systems as well as quantum field theory. Currently,
I am concentrating on the following topics:
(1) High-temperature superconductivity in cuprates (doped Mott insulators) and novel phases of matter;
Quantum Criticality
(2) Quantum field theory in low dimensions; topological quantum field theory

Title: Overlap fermions in the strong coupling limit.
Commentary: This is a simple exercise in my undergraduate period. Prof. Xiang-Qian Luo is a distinguished lattice QCD
expert who passed away on 23 Oct., 2006. He is one of best teachers and hardworking scientists who entirely contributed his life to
education and theoretical physics even after confirmation of cancer.

TItle: Confinement-deconfinement interplay in quantum phases of doped Mott insulators.
Commentary: After the efforts (on nearly every aspect), we finally published this paper in the top leading journal-Physical
Review Letters. In general, it is difficult to publish the high-Tc topics of theoretical aspects on PRL because of the highly controversial
situation of high-Tc community. Salute, Beer!

Title: Electron fractionalization and unconventional order parameters of the t-J model.
Commentary: After the publication of PRL, we prepared this long paper as an extensive article. This paper is very readable
with many technical details. In June 2011, We submitted the paper to the famous NPB journal editorial board and the paper was
eventually accepted in the end of Sep. 2011.

Title: Superconductivity in mutual Chern-Simons gauge theory.
Commentary: This unpublished paper contains the details of effective field theory of superconducting state. We propose a
Wilson-loop-loop correlation function as a direct probe for the "mutual statistics" between spin and charge degrees of freedom.

Title: Chiral gauge field and axial anomaly in a Weyl-semi-metal.
Commentary: We propose condensed-mater-realization of chiral gauge field, axial anomaly, and etc. It is amazing that
condensed matter materials with nontrivial topology can realize the quantum anomaly phenomena but with an effective "speed of light".
