Generalized homology and Atiyah-Hirzebruch spectral sequence in crystalline symmetry protected topological phenomena

arXiv:1810.00801 · doi:10.1093/ptep/ptad086

Abstract

We propose that symmetry protected topological (SPT) phases with crystalline symmetry are formulated by equivariant generalized homologies over a real space manifold with a crystalline symmetry group. The Atiyah-Hirzebruch spectral sequence unifies various notions in crystalline SPT phases such as the layer construction, higher-order SPT phases and Lieb-Schultz-Mattis type theorems. Our formulation is applicable to interacting systems with onsite and crystalline symmetries as well as free fermions.
