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…
Magnetization Plateaus in the Two-dimensional S = 1/2 Heisenberg Model with a 33 Checkerboard Structure
Xuyang Liang, Dao-Xin Yao
We investigate the S=1/2 antiferromagnetic Heisenberg model with a 33 checkerboard lattice structure in a longitudinal magnetic field. By using the stochastic series expans…
