Topological crystalline insulators with C_{2} rotation anomaly
Based on first-principles calculations and a symmetry-based indicator analysis, we find a class of topological crystalline insulators (TCIs) with a C_{2} rotation anomaly in a family of Zintl compounds, including Ba_{3}Cd_{2}As_{4}, Ba_{3}Zn_{2}As_{4}, and Ba_{3}Cd_{2}Sb_{4}. The nontrivial band top...
