Classification of Interacting Topological Crystalline Superconductors in Three Dimensions and Beyond
Shang-Qiang Ning, Xing-Yu Ren, Qing-Rui Wang +2
Although classification for free-fermion topological superconductors (TSC) is established, systematically understanding the classification of 3D interacting TSCs remains difficult,…
Classification of Average Crystalline Topological Superconductors through a Generalized Real-Space Construction
Sarvesh Srinivasan, Jian-Hao Zhang, Yang Qi +1
We investigate a novel class of topological superconducting phases protected by exact fermion-parity symmetry and average crystalline symmetries. These phases belong to the broader…
Parity violation as enforced symmetry breaking in 3D fermionic topological order
Shang-Qiang Ning, Yang Qi, Chenjie Wang +1
Symmetry can be intrinsically broken in topological phases due to inherent incompatibilities, a phenomenon known as enforced symmetry breaking (ESB) in the framework of topological…
Stacking Group Structure of Fermionic Symmetry-Protected Topological Phases
Xing-Yu Ren, Shang-Qiang Ning, Yang Qi +2
In the past decade, there has been a systematic investigation of symmetry-protected topological (SPT) phases in interacting fermion systems. Specifically, by utilizing the concept…
Exactly solvable models for U(1) symmetry-enriched topological phases
Qing-Rui Wang, Meng Cheng
We propose a general construction of commuting projector lattice models for 2D and 3D topological phases enriched by U(1) symmetry, with finite-dimensional Hilbert space per site.…
Computing classification of interacting fermionic symmetry-protected topological phases using topological invariants
Yunqing Ouyang, Qing-Rui Wang, Zheng-Cheng Gu +1
In recent years, great success has been achieved on the classification of symmetry-protected topological (SPT) phases for interacting fermion systems by using generalized cohomolog…
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…
