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…
Universality of Abelian and non-Abelian Wannier functions in one dimension
Kiryl Piasotski, Mikhail Pletyukhov, Clara S. Weber +3
Within a Dirac model in dimensions, a prototypical model to describe low-energy physics for a wide class of lattice models, we propose a field-theoretical version for the rep…
Fractional boundary charges with quantized slopes in interacting one- and two-dimensional systems
Katharina Laubscher, Clara S. Weber, Dante M. Kennes +4
We study fractional boundary charges (FBCs) for two classes of strongly interacting systems. First, we study strongly interacting nanowires subjected to a periodic potential with a…
Chiral 1D Floquet topological insulators beyond rotating wave approximation
Dante M. Kennes, Niclas Müller, Mikhail Pletyukhov +6
We study one-dimensional (1D) Floquet topological insulators with chiral symmetry going beyond the standard rotating wave approximation. The occurrence of many anticrossings betwee…
