Topological Invariants of a Filling-Enforced Quantum Band Insulator

Traditional ionic/covalent compound insulators arise from a commensuration between electron count and system volume. On the other hand, conventional topological insulators, outside of quantum hall effect systems, do not typically display such a commensuration. Tnstead, they can undergo a phase trans...
