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…

Probing topological phase transition with non-Hermitian perturbations
Jingcheng Liang, Chen Fang, Jiangping Hu
We demonstrate that non-Hermitian perturbations can probe topological phase transitions and unambiguously detect non-Abelian zero modes. We show that under carefully designed non-H…
