Logarithmic corrections to bulk and surface criticality in a three-dimensional quantum Heisenberg antiferromagnet
Xuyang Liang, Xiao-Chuan Wu, Zenan Liu +3
The paper investigates how marginally irrelevant interactions produce logarithmic corrections to scaling at the bulk upper critical dimension of a three‑dimensional quantum Heisenb…
Corner Charge Fluctuations in Higher Dimensions
Xiao-Chuan Wu, Pok Man Tam, Xuyang Liang +4
Measuring charge fluctuations within a subregion provides a powerful probe of quantum many-body systems. In two spatial dimensions, the shape dependence of the dimensionless corner…
Worldline deconfinement and emergent long-range interaction in the entanglement Hamiltonian and in the entanglement spectrum
Zenan Liu, Zhe Wang, Dao-Xin Yao +1
The entanglement spectrum (ES) is a powerful tool for probing topological phases. While its behavior in gapped systems is well understood, its properties in gapless regimes remain…
Scaling of the disorder operator at (3+1)D O(3) quantum criticality
Xuyang Liang, Xiao-Chuan Wu, Zenan Liu +3
The disorder operator, as an easily measured nonlocal observable, displays great potential in detecting intrinsic information of field theories. It has been systematically studied…
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 …
Measuring the Boundary Gapless State and Criticality via Disorder Operator
Zenan Liu, Rui-Zhen Huang, Yan-Cheng Wang +2
The disorder operator is often designed to reveal the conformal field theory information in quantum many-body systems. By using large-scale quantum Monte Carlo simulation, we study…
