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…

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…
