Filling-Enforced Quantum Band Insulators in Spin-Orbit Coupled Crystals
Hoi Chun Po, Haruki Watanabe, Michael P. Zaletel +1
While band insulators are usually described in wavevector space in terms of fully filled bands, they are sometimes also described in terms of a complementary Wannier picture in whi…

Filling constraints for spin-orbit coupled insulators in symmorphic and non-symmorphic crystals
Haruki Watanabe, Hoi Chun Po, Ashvin Vishwanath +1
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 f…
