Phases of Quasi-One-Dimensional Fractional Quantum (Anomalous) Hall - Superconductor Heterostructures
Steffen Bollmann, Andreas Haller, Jukka I. Väyrynen +2
Motivated by recent observations of fractional Chern insulators (FCIs) in the vicinity of superconducting (SC) phases, we study fractional quantum (anomalous) Hall-superconductor h…

Multichannel topological Kondo models and their low-temperature conductances
Guangjie Li, Elio J. König, Jukka I. Väyrynen
In the multichannel Kondo effect, overscreening of a magnetic impurity by conduction electrons leads to a frustrated exotic ground state. It has been proposed that multichannel top…
