Dynamical detection of mean-field topological phases in an interacting Chern insulator
Wei Jia, Long Zhang, Lin Zhang +1
Interactions generically have important effects on the topological quantum phases. For a quantum anomalous Hall (QAH) insulator, the presence of interactions can qualitatively chan…
Dynamically characterizing topological phases by high-order topological charges
Wei Jia, Lin Zhang, Long Zhang +1
We propose a new theory to characterize equilibrium topological phase with non-equilibrium quantum dynamics by introducing the concept of high-order topological charges, with novel…
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…
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…
