Normal density and moment of inertia of a moving superfluid
Yi-Cai Zhang, Shu-Wei Song, Gang Chen
In this work, the normal density and moment of inertia of a moving superfluid are investigated. We find that, even at zero temperature, there exists a finite normal density f…
Double-Quantum Spin Vortices in SU(3) Spin-Orbit Coupled Bose Gases
Wei Han, Xiao-Fei Zhang, Shu-Wei Song +4
We show that double-quantum spin vortices, which are characterized by doubly quantized circulating spin currents and unmagnetized filled cores, can exist in the ground states of SU…
Fragmentation of Spin-orbit Coupled Spinor Bose-Einstein Condensates
Shu-Wei Song, Yi-Cai Zhang, Hong Zhao +2
The fragmentation of spin-orbit coupled spin-1 Bose gas with a weak interaction in external harmonic trap is explored by both exact diagonalization and mean-field theory. This frag…
The confinement induced resonance in spin-orbit coupled cold atoms with Raman coupling
Yi-Cai Zhang, Shu-Wei Song, Wu-Ming Liu
We investigate the confinement induced resonance in spin-orbit coupled cold atoms with Raman coupling. We find that the quasi-bound levels induced by the spin-orbit coupling and Ra…
Inhomogeneous spin domain induced by the quadratic Zeeman effect in spin-1 Bose-Einstein condensate
Dun Zhao, Shu-Wei Song, Lin Wen +3
We show two kinds of inhomogeneous spin domain possessing Néel-like domain walls in spin-1 Bose-Einstein condensate, which are induced by the positive and negative quadratic Zeeman…
Zitterbewegung effect in spin-orbit coupled spin-1 ultracold atoms
Yi-Cai Zhang, Song-Wei Song, Chao-Fei Liu +1
The Zitterbewegung effect in spin-orbit coupled spin-1 cold atoms is investigated in the presence of the Zeeman field and a harmonic trap. It is shown that the Zeeman field and the…
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…
Matter rogue wave in Bose-Einstein condensates with attractive atomic interaction
Lin Wen, Lu Li, Zai-Dong Li +3
We investigate the matter rogue wave in Bose-Einstein Condensates with attractive interatomic interaction analytically and numerically. Our results show that the formation of rogue…
Quantized vortices in a rotating Bose-Einstein condensate with spatiotemporally modulated interaction
Deng-Shan Wang, Shu-Wei Song, Bo Xiong +1
We present theoretical analysis and numerical studies of the quantized vortices in a rotating Bose-Einstein condensate with spatiotemporally modulated interaction in harmonic and a…
