Robust dual topological insulator phase in NaZnBi

Robust dual topological insulator phase in NaZnBi

Topological insulators are characterized by Z2 indices, and their metallic surface states are protected by time-reversal symmetry. In topological crystalline insulators, on the other hand, crystal symmetry plays a key role in protecting surface states. Therefore, perturbation breaking time-reversal...
