General Construction from Topological Loop States to Topological Invariants in Exactly Flat Bands
Rui-Heng Liu, Jiangping Hu, Chen Fang
Electronic flat bands have localized Wannier-like orbitals as zero modes. In the Lieb or the kagome models, the localized orbitals satisfy a topological condition that entails two…

Exactly solvable lattice models for interacting electronic insulators in two dimensions
Qing-Rui Wang, Yang Qi, Chen Fang +2
In the past decade, tremendous efforts have been made towards understanding fermionic symmetry protected topological (FSPT) phases in interacting systems. Nevertheless, for systems…

All "Magic Angles" Are "Stable" Topological
Zhida Song, Zhijun Wang, Wujun Shi +3
We show that the electronic structure of the low-energy bands in the small angle-twisted bilayer graphene consists of a series of semi-metallic and topological phases. In particula…
