Superfluid density and collective modes of fermion superfluid in dice lattice
Yu-Rong Wu, Xiao-Fei Zhang, Chao-Fei Liu +2
The superfluid properties of attractive Hubbard model in dice lattice are investigated. It is found that three superfluid order parameters increase as the interaction increases. Wh…
Two-fluid theory for superfluid system with anisotropic effective masses
Yi-Cai Zhang, Chao-Fei Liu, Bao Xu +2
In this work, we generalize the two-fluid theory to a superfluid system with anisotropic effective masses along different principal axis directions. As a specific example, such a t…
Carbon-dioxide-like Skyrmion controlled by spin-orbit coupling in atomic-molecular Bose-Einstein condensates
Chao-Fei Liu, Gediminas Juzeliunas, Wu-Ming Liu
Atomic-molecular Bose-Einstein condensates (BECs) offer brand new opportunities to revolutionize quantum gases and probe the variation of fundamental constants with unprecedented s…
Crystallized and amorphous vortices in rotating atomic-molecular Bose-Einstein condensates
Chao-Fei Liu, Heng Fan, Shih-Chuan Gou +1
Vortex is a topological defect with a quantized winding number of the phase in superfluids and superconductors. Here, we investigate the crystallized (triangular, square, honeycomb…
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…
Spin-orbit coupling induced fractionalized Skyrmion excitations in rotating and rapidly quenched spin-1 Bose-Einstein condensates
Chao-Fei Liu, Wu-Ming Liu
We investigate the fractionalized Skyrmion excitations induced by spin-orbit coupling in rotating and rapidly quenched spin-1 Bose-Einstein condensates. Our results show that the f…
