Measurement protocol for detecting correlated topological insulators in synthetic quantum systems
Yixin Ma, Chao Xu, Shenghan Jiang
Two-dimensional topological insulators, characterized by symmetry-protected anomalous boundary modes, have been generalized to the strongly correlated regime for both bosonic and f…

Diagnosing 2D symmetry protected topological states via mixed state anomaly
Chao Xu, Yunlong Zang, Yixin Ma +2
Symmetry-protected topological (SPT) phases are short-range entangled quantum states characterized by anomalous edge behavior, a manifestation of the bulk-boundary correspondence f…

Controllable suppression of Non-Hermitian skin effects
Xu Chao, Guan Zhiqiang, Xu Hongxing
The non-Hermitian skin effect (NHSE) is a phenomenon where the bulk states tend to the boundary within a non-Hermitian Hamiltonian system, with broad applications across various fi…
