Search for Majorana fermions renewed interest in semiconductor–superconductor interfaces, while a quest for higher-order non-Abelian excitations demands formation of …

We perform a systematic study of Andreev conversion at the interface between a superconductor and graphene in the quantum Hall (QH) regime. We find that the probability …
We study the behavior of the conductance and the current noise in three-terminal configurations of edge modes of a quantum Hall system in the ν= 2 filling factor with normal …
A chiral quantum Hall (QH) edge state placed in proximity to an s-wave superconductor experiences induced superconducting correlations. Recent experiments have observed the …

We review applications of complex band structure theory to describe Majorana states in nanowires and nanowire junctions. The dimensionality of the considered wires is gradually …
We show that a spin-polarized Landau level in a two-dimensional electron gas can carry a spin-triplet supercurrent between two spin-singlet superconductors. The supercurrent results …
Superconductivity and the quantum Hall effect are distinct states of matter occurring in apparently incompatible physical conditions. Recent theoretical developments suggest that …

There has been a growing interest in hybrid quantum Hall–superconductor devices, driven by the prospect to realize exotic ground states and excitations with non-Abelian exchange …
We consider a quantum Hall (QH) region in contact with a superconductor (SC), ie, a QH-SC junction. Due to successive Andreev reflections, the QH-SC interface hosts hybridized …
