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…
