Structure of the mean-field yrast spectrum of a two-component Bose gas in a ring: role of interaction asymmetry
Hui Tang, Guan-Hua Huang, Shizhong Zhang +2
The mean-field yrast spectrum of an SU(2)-symmetric two-component Bose gas confined to a ring geometry is known to exhibit an intricate nonanalytic structure that is absent in sing…
Generalized Onsager reciprocal relations of charge and spin transport
Guan-Hua Huang, Hui Tang, Shizhong Zhang +2
In spin-orbit-coupled systems the charge and spin transport are generally coupled to each other, namely a charge current will induce a spin current and vice versa. In the presence…
Anti-Sisyphus driving in a matter-wave swing
Wen L. Liu, Jun Jian, Ning X. Zheng +6
Dilute-gas Bose-Einstein condensates are an exceptionally versatile testbed for the investigation of physics phenomenon especially the well-known classical system. Here we use a de…
Microgravity-assisted off-axis spin vortex in a Rb dipolar spinor Bose-Einstein condensate
Hui Tang, Wenxian Zhang
The generation of the ground state of a spin vortex in a Rb Bose-Einstein condensate with the assistance of an optical plug has been studied. However, gravity is everywhere,…
Unconventional spin Hall effect in PT symmetric spin-orbit coupled quantum gases
Hui Tang, Guan-Hua Huang, Shizhong Zhang +2
We theoretically study the intrinsic spin Hall effect in PT symmetric, spin-orbit coupled quantum gases confined in an optical lattice. The interplay of the PT symmetry and the spi…
