Magnetononlinear Hall effect from multigap topology in metal-organic frameworks
Chun Wang Chau, Wojciech J. Jankowski, Bo Peng +1
We unveil that non-Abelian multigap band topology characterized by nontrivial Euler class invariants induces observable magnetononlinear Hall transport phenomena. We demonstrate th…

Optical signatures of Euler superconductors
Chun Wang Chau, Wojciech J. Jankowski, Robert-Jan Slager
We study optical manifestations of multigap band topology in multiband superconductors with a nontrivial topological Euler class. We introduce a set of lattice models for non-Abeli…
