Pristine and Pseudo-gapped Boundaries of the Deconfined Quantum Critical Points
Nayan Myerson-Jain, Xiao-Chuan Wu, Cenke Xu
Bulk topology and criticality can both lead to nontrivial boundary effects. Topological orders are often characterized by their robust edge states, while bulk critical points can h…
A construction of exotic metallic states
Xiao-Chuan Wu, Yichen Xu, Mengxing Ye +2
We discuss examples of two dimensional metallic states with charge fractionalization, and we will demonstrate that the mechanism of charge fractionalization leads to exotic metalli…
Universal Features of Higher-Form Symmetries at Phase Transitions
Xiao-Chuan Wu, Chao-Ming Jian, Cenke Xu
We investigate the behavior of higher-form symmetries at various quantum phase transitions. We consider discrete 1-form symmetries, which can be either part of the generalized conc…
Categorical Symmetries at Criticality
Xiao-Chuan Wu, Wenjie Ji, Cenke Xu
We study the concept of "categorical symmetry" introduced recently, which in the most basic sense refers to a pair of dual symmetries, such as the Ising symmetries of the quan…
Physics of Symmetry Protected Topological phases involving Higher Symmetries and their Applications
Chao-Ming Jian, Xiao-Chuan Wu, Yichen Xu +1
We discuss physical constructions, and the boundary properties of various symmetry protected topological phases that involve 1-form symmetries, from one spatial dimension (1d) to f…
Continuous Néel-VBS Quantum Phase Transition in Non-Local one-dimensional systems with SO(3) Symmetry
Chao-Ming Jian, Yichen Xu, Xiao-Chuan Wu +1
One dimensional interacting systems with local Hamiltonians can be studied with various well-developed analytical methods. Recently novel physics was found numerically…
