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…
Universal properties of boundary and interface charges in multichannel one-dimensional continuum models
Kiryl Piasotski, Niclas Müller, Dante M. Kennes +2
We generalize our recent results for the boundary and interface charges in one-dimensional single-channel continuum [Phys. Rev. B 104, 155409 (2021)] and multichannel tight-binding…
Floquet Renormalization Group Approach to the Periodically Driven Kondo Model
Valentin Bruch, Mikhail Pletyukhov, Herbert Schoeller +1
We study the interplay of strong correlations and coherent driving by considering the strong-coupling Kondo model driven by a time-periodic bias voltage. Combining a recent nonequi…
Quantum dot coupled to topological insulators: The role of edge states
Martin T. Maurer, Yen-Ting Lin, Dante M. Kennes +3
We investigate a system consisting of one or two topological-insulator leads which are tunnel coupled to a single dot level. The leads are described by the one-dimensional Su-Schri…
