Ratchet current in a -symmetric Floquet quantum system with symmetric sinusoidal driving
Zhiqiang Li, Xiaoxiao Hu, Jinpeng Xiao +2
We consider the ratchet dynamics in a -symmetric Floquet quantum system with symmetric temporal (harmonic) driving. In the exact phase, for a finite nu…
Scattering of one-dimensional quantum droplets by a reflectionless potential well
Xiaoxiao Hu, Zhiqiang Li, Yu Guo +2
We investigate, both analytically and numerically, the scattering of one-dimensional quantum droplets by a Pöschl-Teller reflectionless potential well, confirming that there is a s…
Spin Josephson effects of spin-orbit-coupled Bose-Einstein condensates in a non-Hermitian double well
Jia Tang, Zhou Hu, Zhao-Yun Zeng +5
In this paper, we investigate the spin and tunneling dynamics of a spin-orbit-coupled noninteracting Bose-Einstein condensate in a periodically driven non-Hermitian double-well pot…
Phase control of localization in the nonlinear two-mode system from harmonic mixing driving: Perturbative analysis and symmetry consideration
Xianchao Le, Zhao-Yun Zeng, Baiyuan Yang +7
In this paper, we present a rigorous analysis of symmetry and underlying physics of the nonlinear two-mode system driven by a harmonic mixing field, by means of multiple scale asym…
The topological invariants in 2D and 3D topological superconductors without time reversal symmetry
Jinpeng Xiao, Qianglin Hu, Huiqiong Zeng +1
In theory of topological classification, the 2D topological superconductors without time reversal symmetry are characterized by Chern numbers. However, in reality, we find the Cher…
Analytical results for the superflow of spin-orbit-coupled Bose-Einstein condensates in optical lattices
Xiaobing Luo, Zhou Hu, Zhao-Yun Zeng +5
In this paper, we show that for sufficiently strong atomic interactions, there exist analytical solutions of current-carrying nonlinear Bloch states at the Brillouin zone edge to t…
