Screw-pitch effect and velocity oscillation of domain-wall in ferromagnetic nanowire driven by spin-polarized current
Zai-Dong Li, Qiu-Yan Li, X. R. Wang +3
We investigate the dynamics of domain wall in ferromagnetic nanowire with spin-transfer torque. The critical current condition is obtained analytically. Below the critical current,…
Domain-wall solutions of spinor Bose-Einstein condensates in an optical lattice
Zai-Dong Li, Qiu-Yan Li, Peng-Bin He +3
We studied the static and dynamic domain wall solutions of spinor Bose-Einstein condensates trapped in an optical lattice. The single and double domain wall solutions are construct…
A binary mixture of spinor atomic Bose-Einstein condensates
Z. F. Xu, Yunbo Zhang, L. You
We study the ground state and classify its phase diagram for a mixture of two spin-1 condensates in the absence of external magnetic (B-) field according to atomic parameters for i…
Atom-Pair Tunneling and Quantum Phase Transition in Strong Interaction Regime
J. -Q. Liang, J. -L. Liu, W. -D. Li +1
We propose a Hamiltonian of ultracold spinless atoms in optical lattices including the two-body interaction of nearest neighbors, which reduces to the Bose-Hubbard model in weak in…
The stability and free expansion of a dipolar Fermi gas
L. He, J. -N. Zhang, Yunbo Zhang +1
We investigate the stability and the free expansion of a trapped dipolar Fermi gas. We show that stabilizing the system relying on tuning the trap geometry is generally inefficient…
Soliton Solution for the Spin Current in Ferromagnetic Nanowire
Zai-Dong Li, Qiu-Yan Li, Lu Li +1
We investigate the interaction of a periodic solution and one-soliton solution for the spin-polarized current in a uniaxial ferromagnetic nanowire. The amplitude and wave number of…
