Deconfined Quantum Phase Transition of a Higher-Order Symmetry-Protected Topological State
Chen Peng, Long Zhang, Zhong-Yi Lu
A higher-order (HO) symmetry-protected topological (SPT) state can be realized in a plaquette-modulated square lattice antiferromagnet, which hosts a spin- degenerate mode on…
Stability of dynamical topology against dynamical noise in quantum quenches
Lin Zhang, Long Zhang, Xiong-Jun Liu
Equilibrium topological phases are robust against weak static disorder but may break down in the strong disorder regime. Here we explore the stability of the quench-induced emergen…
Unified theory to characterize Floquet topological phases by quench dynamics
Long Zhang, Lin Zhang, Xiong-Jun Liu
The conventional characterization of periodically driven systems usually necessitates the time-domain information beyond Floquet bands, hence lacking universal and direct schemes o…
One dimensional quasiperiodic mosaic lattice with exact mobility edges
Yucheng Wang, Xu Xia, Long Zhang +5
The mobility edges (MEs) in energy which separate extended and localized states are a central concept in understanding the localization physics. In one-dimensional (1D) quasiperiod…
Quantum simulation for three-dimensional chiral topological insulator
Wentao Ji, Lin Zhang, Mengqi Wang +8
Quantum simulation, as a state-of-art technique, provides the powerful way to explore topological quantum phases beyond natural limits. Nevertheless, a previously-not-realized thre…
Realization and detection of non-ergodic critical phases in optical Raman lattice
Yucheng Wang, Long Zhang, Sen Niu +2
The critical phases, being delocalized but non-ergodic, are fundamental phases which are different from both the many-body localization and ergodic extended quantum phases, and hav…
