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…
Diffusive Excitonic Bands from Frustrated Triangular Sublattice in a Singlet-Ground-State System
Bin Gao, Tong Chen, Xiao-Chuan Wu +17
Magnetic order in most materials occurs when magnetic ions with finite moments in a crystalline lattice arrange in a particular pattern below the ordering temperature determined by…
Deconfined Quantum Critical Point with Non-locality
Yichen Xu, Xiao-Chuan Wu, Cenke Xu
The deconfined quantum critical point (DQCP) between the Néel and valence bond solid (VBS) order was originally proposed in quantum spin systems with a local Hamiltonian. In the la…
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…

Yichen Xu, Xiao-Chuan Wu, Mengxing Ye +3
It has been proposed that an extended version of the Hubbard model which potentially hosts rich correlated physics may be well simulated by the transition metal dichalcogenide (TMD…
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…

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…
Topological Edge and Interface states at Bulk disorder-to-order Quantum Critical Points
Yichen Xu, Xiao-Chuan Wu, Chao-Ming Jian +1
We study the interplay between two nontrivial boundary effects: (1) the two dimensional () edge states of three dimensional () strongly interacting bosonic symmetry protect…
Boundary Criticality of Topological Quantum Phase Transitions in systems
Xiao-Chuan Wu, Yichen Xu, Hao Geng +2
We discuss the boundary critical behaviors of two dimensional quantum phase transitions with fractionalized degrees of freedom in the bulk, motivated by the fact that usually it is…

Yichen Xu, Hao Geng, Xiao-Chuan Wu +2
Non-fermi liquid and unconventional quantum critical points (QCP) with strong fractionalization are two exceptional phenomena beyond the classic condensed matter doctrines, both of…

Motivated by recent observation of nematicity in Moiré systems, we study three different orbital orders that potentially can happen in Moiré systems: (1) the nematic order; (2) the…
