Enforced symmetry breaking by invertible topological order
Shang-Qiang Ning, Yang Qi, Zheng-Cheng Gu +1
It is well known that two-dimensional fermionic systems with a nonzero Chern number must break the time reversal symmetry, manifested by the appearance of chiral edge modes on an o…

Anomaly indicators and bulk-boundary correspondences for 3D interacting topological crystalline phases with mirror and continuous symmetries
Shang-Qiang Ning, Bin-Bin Mao, Zhengqiao Li +1
We derive a series of quantitative bulk-boundary correspondences for 3D bosonic and fermionic symmetry-protected topological (SPT) phases under the assumption that the surface is g…
