Bipartite entanglement and surface criticality: The extra contribution of non-ordinary edge in entanglement
Yanzhang Zhu, Zenan Liu, Zhe Wang +2
Recent works on the scaling behaviors of entanglement entropy at the SO(5) deconfined quantum critical point (DQCP) sparked a huge controversy. Different bipartitions gave out tota…

Detecting underlying symmetry-protected topological phases via strange correlators and edge engineering
Zhe Wang, Longye Lu, Shang-Qiang Ning +4
The vast majority of symmetry-protected topological (SPT) states are difficult to detect, which often leads to their misidentification as ordinary or topologically trivial phases.…

Singularity and universality from von Neumann to Rényi entanglement entropy and disorder operator in Motzkin chains
Jianyu Wang, Zenan Liu, Zheng Yan +1
The Rényi entanglement entropy is widely used in studying quantum entanglement properties in strongly correlated systems, whose analytic continuation as the Rényi index i…
