Excitation Spectra and Hard-core Thermodynamics of Bosonic Atoms In Double Well Optical Lattices
Bao Xu, Hong-Ye Wu, Yi-Cai Zhang +2
A general coupled representation is proposed for bosonic atoms in double well optical lattices. Based on such a representation, we investigate the excitation spectra and thermodyna…
Ground state of spin-1 Bose-Einstein condensates with spin-orbit coupling in a Zeeman field
L. Wen, Q. Sun, H. Q. Wang +2
We systematically investigate the weakly trapped spin-1 Bose-Einstein condensates with spin-orbit coupling in an external Zeeman field. We find that the mean-field ground state fav…
Spin-orbit coupling induced separation and hidden spin textures in spin-1 Bose-Einstein condensates
Shu-Wei Song, Yi-Cai Zhang, Qing Sun +4
We analytically and numerically investigate the ground state of the spin-orbit coupled spin-1 Bose-Einstein condensates in an external parabolic potential. When the spin-orbit coup…
Particle-hole bound states of dipolar molecules in optical lattice
Yi-Cai Zhang, Han-Ting Wang, Shun-Qing Shen +1
We investigate the particle-hole pair excitations of dipolar molecules in optical lattice, which can be described with an extended Bose-Hubbard model. For strong enough dipole-dipo…
Generation of ring dark solitons by phase engineering and their oscillations in spin-1 Bose-Einstein condensates
Shu-Wei Song, Deng-Shan Wang, Hanquan Wang +1
The ring dark solitons in spin-1 Na and Rb Bose-Einstein condensates are studied numerically in the framework of the time-dependent Gross-Pitaevskii equations. By sim…
Efficient numerical methods for computing ground states and dynamics of dipolar Bose-Einstein condensates
Weizhua Bao, Yongyong Cai, Hanquan Wang
New efficient and accurate numerical methods are proposed to compute ground states and dynamics of dipolar Bose-Einstein condensates (BECs) described by a three-dimensional (3D) Gr…
