-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…

Crossover or First-Order: Impacts of Regularization
Xin-Peng Li, Hao-Ran Zhang, Zhu-Fang Cui +1
The equation of state of hot, dense nuclear matter plays a fundamental role in many areas. However, owing to the nonperturbative nature of strong interactions, a reliable treatment…

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…
