Magnetic flux induced higher-order topological superconductivity
Jinpeng Xiao, Qianglin Hu, Zuodong Yu +2
Higher-order topological superconductivity typically depends on spin-orbit interaction, and often necessitates well designed sample structures, nodal superconducting pairings or co…
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…

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.…
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…
Magnetic flux induced topological superconductivity in magnetic atomic rings

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…
