| Career History: |
Male, born in 1971 at Hanzhou China. received bachelor and master degree respectively in 1993 and 1996 at ZheJiang University, and then PHD in 1999 at institute of theoretical physics, Chinese academic society (ITP, CAS). In 1999 to 2005, He had visited many advanced research institutions in Hong Kong, the United States and some other countries. In 2005 he was selected by "Hundred Talents" of Chinese Academic Society (CAS), and return to work in the Institute of Physics, Chinese Academy of Sciences as a professor. |

| Research Experience |
1. In the United States, developed a set of density functional theory combined with dynamical mean field theory package, and applied this package to metal Pu, get a lot of reasonable and important results. 2. Propose an experimental method to directly detect pseudo gap in high-Tc superconductors. studied the current noise spectra of a tunnel junction of a metal with strong pairing phase fluctuation and a superconductor. In the presence of an ac voltage, the tunneling current noise shows a series of characteristic peaks with increasing dc voltage. Experimental observation of these peaks will give direct evidence of the pair fluctuation in the normal state of high- Tc superconductors and the pair decay rate can be estimated from the half width of the peaks. 3. In my study of high Tc superconductor, puts forward Fermi-surface evolution theory at underdoping region. In the context of the t-J model, we show that besides the long wave length gauge field fluctuation, an additional low energy fluctuation, i.e., the staggered gauge field fluctuation, plays a crucial role in the underdoped regime. Our results are consistent with ARPES experiments. Many studies published in first-class international journal. (include Phys. Rev. Lett. and SCIENCE). |
