Topological bands in one-dimensional periodic potentials
Yi Zheng, Shi-Jie Yang
We study the properties of the quantum states in the one-dimensional system with a shifted periodic potential in both the discrete model and the continuous model. With open boundar…
Resonantly enhanced coherence by laser-assisted tunneling
Hong-Xia Hao, Shiping Feng, Shi-Jie Yang
We study quantum coherence of strongly interacting cold bosons in a double-well potential driven by a laser field. The system is initially in a Fock state and, for either with or w…
Exact solitons and manifold mixing dynamics in the spin-orbit-coupled spinor condensates
Yong-Kai Liu, Shi-Jie Yang
We derive exact static as well as moving solitonic solutions to the one-dimensional spin-orbit-coupled F=1 Bose-Einstein condensates. The static polar soliton is shown to be the gr…
Stable knots in the trapped Bose-Einstein condensates
Yong-Kai Liu, Shiping Feng, Shi-Jie Yang
The knot of spin texture is studied within the two-component Bose-Einstein condensates which are described by the nonlinear Gross-Pitaevskii equations. We start from the non-intera…
Dynamical revivals of the paired superfluidity and counterflow superfluidity
Shi-Jie Yang, Pei Lu, Shiping Feng
The quantum dynamics of two-species bosons in an optical lattice is studied within the mean-field theory. The quantum coherence experiences periodical collapses and revivals, which…
Exact periodic and solitonic states in the spinor condensates
Zhi-Hai Zhang, Shi-Jie Yang
We propose a method to analytically solve the one-dimensional coupled nonlinear Gross-Pitaevskii equations which govern the motion of the spinor Bose-Einstein condensates. In a uni…
