Controlling the Symmetry Breaking Threshold in Bipartite Lattice Systems with Floquet Topological Edge States
Xinguang Li, Hongzheng Wu, Yangchun Zhao +5
We investigate the control of the parity-time ()-symmetry breaking threshold in a periodically driven one-dimensional dimerized lattice with spatially symmetric gain…
Generation and Stabilization of Bound States in the Continuum in Dissipative Floquet Optical Lattices
Yangchun Zhao, Hongzheng Wu, Xinguang Li +5
This paper investigates the generation and stabilization of bound states in the continuum (BICs) in a one-dimensional dissipative Floquet lattice. We find a different mechanism for…
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…
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…
Controlling directed atomic motion and second-order tunneling of a spin-orbit-coupled atom in optical lattices
Xiaobing Luo, Zhao-Yun Zeng, Yu Guo +5
We theoretically explore the tunneling dynamics for the tight-binding (TB) model of a single spin-orbit-coupled atom trapped in an optical lattice subjected to lattice shaking and…
Coherent control of dissipative dynamics in a periodically driven lattice array
Zhao-Yun Zeng, Lei Li, Baiyun Yang +2
We find a different mechanism for suppression of decay in an open one-dimensional lattice system, which originates from a dark Floquet state, a sink state to which the system is as…
Dynamics of spin-orbit-coupled cold atomic gases in a Floquet lattice with an impurity
Xiaobing Luo, Baiyuan Yang, Jin Cui +3
In this study, we have studied the quantum tunneling of a single spin-orbit-coupled atom held in a periodically modulated optical lattice with an impurity. At the pseudocollapse po…
Analytical results for a parity-time symmetric two-level system under synchronous combined modulations
Xiaobing Luo, Baiyuan Yang, Xiaofei Zhang +2
We propose a simple method of combined synchronous modulations to generate the analytically exact solutions for a parity-time symmetric two-level system. Such exact solutions are e…
Mixed-gap vector solitons in PT-symmetric lattices with saturable nonlinearity
Lei Li, Xiaoguang Yu, Xing Zhu +3
We have investigated mixed-gap vector solitons involving incoherently coupled fundamental and dipole components in a parity-time (PT) symmetric lattice with saturable nonlinearity.…
