Logarithmic corrections to bulk and surface criticality in a three-dimensional quantum Heisenberg antiferromagnet
Xuyang Liang, Xiao-Chuan Wu, Zenan Liu +3
At the bulk upper critical dimension, marginally irrelevant interactions generate multiplicative logarithmic corrections to mean-field scaling. While these corrections are well und…
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…
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…
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…
