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…

Higher-Matter and Landau-Ginzburg Theory of Higher-Group Symmetries
Ruizhi Liu, Ran Luo, Yi-Nan Wang
Higher-matter is defined by higher-representation of a symmetry algebra, such as the -form symmetries, higher-group symmetries or higher-categorical symmetries. In this paper, w…

Entanglement area law and Lieb-Schultz-Mattis theorem in long-range interacting systems, and symmetry-enforced long-range entanglement
Ruizhi Liu, Jinmin Yi, Shiyu Zhou +1
We establish multiple interrelated, fundamental results in quantum many-body systems that can have long-range interactions. For a sufficiently long quantum spin chain, we first sho…
