Fractional corner charges in threefold-symmetric two-dimensional materials with fragile topology
Olga Arroyo-Gascón, Sergio Bravo, Leonor Chico +1
We perform a systematic study of the signatures of fragile topology in over 50 nonmagnetic two-dimensional materials with formula AB, belonging to space group -. Using…
