Non-Abelian multigap topology with Euler class invariants in kagome NHC MOFs induces a controllable magnetononlinear Hall effect.
Quantum geometric semimetals produce instantaneous steady-state current under electric fields via interband coupling from Hilbert-Schmidt quantum distance and finite density of states at band-touching points, outperforming metals, semiconductors, and graphene in switching speed.
