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-orbit coupling mediated photon-like resonance for a single atom trapped in a symmetric double well
Changwei Fan, Xiaoxiao Hu, Xin Yan +5
We employ a method involving coherent periodic modulation of Raman laser intensity to induce resonance transitions between energy levels of a spin-orbit coupled atom in a symmetric…
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…
