Point-group symmetry enriched topological orders
Zhaoyang Ding, Yang Qi
We study the classification of two-dimensional (2D) topological orders enriched by point-group symmetries, by generalizing the folding appraoch which was previously developed for m…
Fermi arcs and pseudogap in a lattice model of a doped orthogonal metal
Chuang Chen, Tian Yuan, Yang Qi +1
Since the discovery of the pseudogap and Fermi arc states in underdoped cuprates, the understanding of such non-Fermi-liquid states and the associated violation of Luttinger's theo…
Classification of symmetry fractionalization in gapped spin liquids
Yang Qi, Meng Cheng
In quantum spin liquids, fractional spinon excitations carry half-integer spins and other fractional quantum numbers of lattice and time-reversal symmetries. Different patterns of…
Superconductivity from a confinement transition out of a fractionalized Fermi liquid with topological and Ising-nematic orders
Shubhayu Chatterjee, Yang Qi, Subir Sachdev +1
The Schwinger-boson theory of the frustrated square lattice antiferromagnet yields a stable, gapped spin liquid ground state with time-reversal symmetry, incommensur…
Classification and detection of symmetry fractionalization in chiral spin liquids
Lukasz Cincio, Yang Qi
In this work we study the crystal symmetry fractionalization in chiral spin liquids with the chiral-semion topological order. We show that if such a chiral spin liquid is realized…
Spin Liquid Phases for Spin-1 systems on the Triangular lattice
Cenke Xu, Fa Wang, Yang Qi +2
Motivated by recent experiments on material Ba3NiSb2O9, we propose two novel spin liquid phases (A and B) for spin-1 systems on a triangular lattice. At the mean field level, both…
