Space group symmetry fractionalization in a chiral kagome Heisenberg antiferromagnet
Michael P. Zaletel, Zhenyue Zhu, Yuan-Ming Lu +2
The anyonic excitations of a spin-liquid can feature fractional quantum numbers under space-group symmetries. Detecting these fractional quantum numbers, which are analogs of the f…
Are the double Fermi arcs of Dirac semimetals topologically protected?
Mehdi Kargarian, Mohit Randeria, Yuan-Ming Lu
Motivated by recent experiments probing anomalous surface states of Dirac semimetals (DSMs) NaBi and CdAs, we raise the question posed in the title. We find that, in ma…
Bulk invariants and topological response in insulators and superconductors with nonsymmorphic symmetries
Daniel Varjas, Fernando de Juan, Yuan-Ming Lu
In this work we consider whether nonsymmorphic symmetries such as a glide plane can protect the existence of topological crystalline insulators and superconductors in three dimensi…
Symmetric spin liquids and their neighboring phases on triangular lattice
Yuan-Ming Lu
Motivated by recent numerical discovery of a gapped spin liquid phase in spin- triangular-lattice - Heisenberg model, we classify symmetric spin liquids on tri…
Quantum Phase Transitions Between a Class of Symmetry Protected Topological States
Lokman Tsui, Hong-Chen Jiang, Yuan-Ming Lu +1
The subject of this paper is the phase transition between symmetry protected topological states (SPTs). We consider spatial dimension and symmetry group so that the cohomol…
Measuring space-group symmetry fractionalization in Z spin liquids
Michael Zaletel, Yuan-Ming Lu, Ashvin Vishwanath
The interplay of symmetry and topological order leads to a variety of distinct phases of matter, the Symmetry Enriched Topological (SET) phases. Here we discuss physical observable…
