Inversion-symmetry protected chiral hinge states in stacks of doped quantum Hall layers

Sander H. Kooi, Guido van Miert, Carmine Ortix

We prove the existence of higher-order topological insulators with protected chiral hinge modes in quasi-two-dimensional systems made out of coupled layers stacked in an inversion-…

Genesis of the Floquet Hofstadter butterfly

S. H. Kooi, A. Quelle, W. Beugeling +1

We investigate theoretically the spectrum of a graphene-like sample (honeycomb lattice) subjected to a perpendicular magnetic field and irradiated by circularly polarized light. Th…
