Critical velocities for a superfluid in a periodic potential (2006)
In contrast to the homogeneous superfluid which has only one critical velocity, there exist two critical velocities for a superfluid in a periodic potential. The first one, which we call inside...
Reply to Comment on "Berry phase correction to electron density of states in solids" (2006)
Xiao, Di, Shi, Junren, Niu, Qian
The Comment by Duval et al. [PRL 96, 099701 (2006)] addresses an important, but not the main, result of our Letter [PRL 95, 137204 (2005)]. It does not contradict our results in substance, and the...
Attractive electron-electron interaction induced by geometric phase in a Bloch band (2006)
We investigate electron pairing in the presence of the Berry curvature field that ubiquitously exists in ferromagnetic metals with spin-orbit coupling. We show that a sufficiently strong Berry...
On A Proper Definition of Spin Current (2005)
Shi, Junren, Zhang, Ping, Xiao, Di, Niu, Qian
The conventional definition of spin current is incomplete and unphysical in describing spin transport in systems with spin-orbit coupling. A proper and measurable spin current is established in this...
Berry phase correction to electron density of states in solids (2005)
Xiao, Di, Shi, Junren, Niu, Qian
Liouville's theorem on the conservation of phase space volume is violated by Berry phase in the semiclassical dynamics of Bloch electrons. This leads to a modification of the phase space density of...

Shi, Junren, Wu, Biao, Xie, X. C., Plummer, E. W., Zhang, Zhenyu
We propose that the indirect adatom-adatom interaction mediated by the conduction electrons of a metallic surface is responsible for the $\sqrt{3}\times \sqrt{3}\Leftrightarrow 3\times 3$ structural...
We show that the comment by A.F. Volkov ignores a delicate issue in the conductance measurement for a hall bar system. In such system, $\rho _{xx}\approx \rho_{xy}^{2}\sigma_{xx}$ while...
