Dynamics of Dipolar Spinor Condensates
Rong Cheng, J. -Q. Liang, Yunbo Zhang
We study the semiclassical dynamics of a spinor condensate with the magnetic dipole-dipole interaction included. The time evolution of the population imbalance and the relative pha…

Superfluidity of spin-1 bosons in optical lattices
Rong Cheng, J. -Q. Liang
In this paper we show that the superfluidity of cold spin--1 Bose atoms of weak interactions in an optical lattice can be realized according to the excitation energy spectrum which…
