Exact solutions to the spin-2 Gross-Pitaevskii equations
Zhi-Hai Zhang, Yong-Kai Liu, Shi-Jie Yang
We present several exact solutions to the coupled nonlinear Gross-Pitaevskii equations which describe the motion of the one-dimensional spin-2 Bose-Einstein condensates. The nonlin…
Impurity effects on the quantum coherence of a few-boson system
Pei Lu, Zhi-Hai Zhang, Shiping Feng +1
The impurity effects on the quantum coherence of a few-boson system are studied within the two-site Hubbard model. Periodical collapses and revivals of coherence occur in the prese…
Analytical solutions to the spin-1 Bose-Einstein condensates
Zhi-Hai Zhang, Cong Zhang, Shi-Jie Yang +1
We analytically solve the one-dimensional coupled Gross-Pitaevskii equations which govern the motion of F=1 spinor Bose-Einstein condensates. The nonlinear density-density interact…
Disorder effects on the quantum coherence of a many-boson system
Zhi-Hai Zhang, Pei Lu, Shiping Feng +1
The effects of disorders on the quantum coherence for many-bosons are studied in a double well model. For the ground state, the disorder enhances the quantum coherence. In the deep…
Thermodynamical properties of a trapped interacting Bose gas
Shi-Jie Yang, Yuechan Liu, Shiping Feng
The thermodynamical properties of interacting Bose atoms in a harmonic potential are studied within the mean-field approximation. For weak interactions, the quantum statistics is e…
