Higher obstructions to conformal boundary conditions and lattice realizations
Ruizhi Liu, Weicheng Ye
Although it is long believed that vanishing of chiral central charges of a 2d conformal field theory (CFT) implies the existence of conformal boundary conditions, there are yet hig…
Crystallography, Group Cohomology, and Lieb-Schultz-Mattis Constraints
Chunxiao Liu, Weicheng Ye
We present a computational study of the mod-2 cohomology of three-dimensional (3D) space groups, with an eye toward their applications in Lieb--Schultz--Mattis constraints. We prov…
Why Groups Matter: Necessity of Group Structures in Attributions
Dangxing Chen, Jingfeng Chen, Weicheng Ye
Explainable machine learning methods have been accompanied by substantial development. Despite their success, the existing approaches focus more on the general framework with no pr…
Topological holography for fermions
Rui Wen, Weicheng Ye, Andrew C. Potter
Topological holography is a conjectured correspondence between the symmetry charges and defects of a -dimensional system with the anyons in a -dimensional topological ord…
