Reflection and time reversal symmetry enriched topological phases of matter: path integrals, non-orientable manifolds, and anomalies
Maissam Barkeshli, Parsa Bonderson, Chao-Ming Jian +2
We study symmetry-enriched topological (SET) phases in 2+1 space-time dimensions with spatial reflection and/or time-reversal symmetries. We provide a systematic construction of a…
Topological Quantum Computation with Gapped Boundaries
Iris Cong, Meng Cheng, Zhenghan Wang
This paper studies fault-tolerant quantum computation with gapped boundaries. We first introduce gapped boundaries of Kitaev's quantum double models for Dijkgraaf-Witten theories u…
A series of (2+1)d Stable Self-Dual Interacting Conformal Field Theories
Meng Cheng, Cenke Xu
Using the duality between seemingly different (2+1)d conformal field theories (CFT) proposed recently, we study a series of (2+1)d stable self-dual interacting CFTs. These CFTs can…
Ising Anyons in Frustration-Free Majorana-Dimer Models
Brayden Ware, Jun Ho Son, Meng Cheng +3
Dimer models have long been a fruitful playground for understanding topological physics. Here we introduce a new class - termed Majorana-dimer models - wherein bosonic dimers are d…
Exactly Solvable Models for Symmetry-Enriched Topological Phases
Meng Cheng, Zheng-Cheng Gu, Shenghan Jiang +1
We construct fixed-point wave functions and exactly solvable commuting-projector Hamiltonians for a large class of bosonic symmetry-enriched topological (SET) phases, based on the…
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…
