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 …

Thin films of ferromagnetic topological insulator materials can host the quantum anomalous
Hall effect without the need for an external magnetic field. Inducing Cooper pairing in such a …

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 investigate the interplay between the quantum Hall (QH) effect and superconductivity in
InAs surface quantum well (SQW)/NbTiN heterostructures using a quantum point contact …

In graphene, the approximate SU (4) symmetry associated with the spin and valley degrees
of freedom in the quantum Hall (QH) regime is reflected in the fourfold degeneracy of …

Separating heat from charge in a material is an extremely challenging task since they are
transported by the very same carriers, ie electrons or holes. In this Letter we show that such …

We have fabricated a superconductor/semiconductor junction composed of Al and InAs
using cleaved edge overgrowth (CEO). By exploiting the unique geometry with a thin Al/Pt/Al …

Since the discovery of the quantum Hall (QH) effect, physicists have realized that the
distinction between an insulator and a conductor is not as simple as the band theory of …

Unidirectional and backscatter-free propagation of charge carriers in three-dimensional
materials is of fundamental interest in physics and high demand for practical …
