-type Lieb-Schultz-Mattis anomalies, deconfined quantum critical points, and non-invertible symmetry breaking
Hao-Ran Zhang, Hanlin Lin, Shuo Yang +1
We study deconfined quantum critical points (DQCP) associated with Lieb-Schultz-Mattis (LSM) anomalies in one-dimensional spin chains. Our starting point is a structural characteri…
Boundary anomaly detection in two-dimensional subsystem symmetry-protected topological phases
Ke Ding, Hao-Ran Zhang, Bai-Ting Liu +1
We generalize the topological response theory to detect the boundary anomalies of linear subsystem symmetries. This approach allows us to distinguish different subsystem symmetry-p…
Intrinsically Interacting Higher-Order Topological Superconductors
Hao-Ran Zhang, Jian-Hao Zhang, Zheng-Cheng Gu +2
We propose a minimal interacting lattice model for two-dimensional class- higher-order topological superconductors with no free-fermion counterpart. A Lieb-Schultz-Mattis-type c…
