New classes of topological crystalline insulators having surface rotation anomaly
We discover new types of quantum anomalies in two-dimensional systems with time-reversal symmetry (T) and discrete rotation symmetry with order of n = 2, 4, and 6 (C(n)). The new anomalous states have n flavors of massless Dirac fermions protected by T and C(n), whereas any two-dimensional lattices...
