Fractional corner charges in threefold-symmetric two-dimensional materials with fragile topology
We perform a systematic study of the signatures of fragile topology in over 50 nonmagnetic two-dimensional materials with formula AB_{2}, belonging to space group P3[over ¯]m1. Using group theory analysis in the framework of topological quantum chemistry, we find fragile bands near the Fermi level f...
