This review discusses the electronic properties and the prospective research directions of
superconductor-graphene heterostructures. The basic electronic properties of graphene are …

The search for topological excitations such as Majorana fermions has spurred interest in the
boundaries between distinct quantum states. Here, we explore an interface between two …

We have realized an integer quantum Hall system with superconducting contacts by
connecting graphene to niobium electrodes. Below their upper critical field of 4 T, an integer …

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 …

The single-particle excitations of a superconductor are coherent superpositions of electrons
and holes near the Fermi level, called Bogoliubov quasiparticles. They are Majorana …

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 …

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 …

A quantum Hall interferometer containing a grounded superconducting terminal is proposed.
This geometry allows to control the Andreev and normal scattering amplitudes of subgap …

We experimentally studied the Josephson supercurrent in Nb/InN-nanowire/Nb junctions.
Large critical currents up to 5.7 μ A have been achieved, which proves the good coupling of …

We study narrow ballistic Josephson weak links in a InAs quantum wells contacted by Nb
electrodes and find a dramatic magnetic-field suppression of the Andreev reflection …
