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…
Quantum-classical correspondence of non-Hermitian spin-orbit coupled bosonic junction
Xin Yan, Hongzheng Wu, Changwei Fan +5
We investigate the classical-quantum correspondence of non-Hermitian Spin-orbit (SO)-coupled bosonic junctions, where an effective decay term is introduced in one of the two wells.…
Photon-assisted tunneling resonantly controlling spin current of a spin-orbit-coupled atom in a toroidal trap
Zhiqiang Li, Xiaoxiao Hu, Zhao-Yun Zeng +2
The periodic flashing potential has proven to be a powerful tool for investigating directed atomic currents. By applying the flashing ring-shaped potential to spin-orbit (SO) coupl…
Chaos signatures of current phase transition in a toroidal trap
Zhiqiang Li, Xiaoxiao Hu, Zhao-Yun Zeng +3
In this work we demonstrate how the directed motion of atomic Bose-Einstein condensates in a toroidal trap can be controlled by applying a zero-mean oscillatory driving field. We s…

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…
