Realization of a three-dimensional quantum Hall effect in a Zeeman-induced second order topological insulator on a torus
Zhe Hou, Clara S. Weber, Dante M. Kennes +4
We propose a realization of a quantum Hall effect (QHE) in a second-order topological insulator (SOTI) in three dimensions (3D), which is mediated by hinge states on a torus surfac…
Second-order topology and supersymmetry in two-dimensional topological insulators
Clara S. Weber, Mikhail Pletyukhov, Zhe Hou +4
We unravel a fundamental connection between supersymmetry and a wide class of two dimensional second-order topological insulators (SOTI). This particular supersymmetry is induced b…
RKKY interaction in one-dimensional flat-band lattices
Katharina Laubscher, Clara S. Weber, Maximilian Hünenberger +4
We study the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction between two classical magnetic impurities in one-dimensional lattice models with flat bands. As two representative exa…
