Filling constraints for spin-orbit coupled insulators in symmorphic and nonsymmorphic crystals
We determine conditions on the filling of electrons in a crystalline lattice to obtain the equivalent of a band insulator—a gapped insulator with neither symmetry breaking nor fractionalized excitations. We allow for strong interactions, which precludes a free particle description. Previous approach...
