Electronic Fabry-Pérot interferometry is a powerful method to probe quasiparticle charge
and anyonic braiding statistics in the fractional quantum Hall regime. We extend this …

In the fractional quantum Hall effect, quasiparticles are collective excitations that have a
fractional charge and show fractional statistics as they interchange positions. While the …

In the last decade, graphene has become an exciting platform for electron optical
experiments, in some aspects superior to conventional two-dimensional electron gases …

The search for anyons, quasiparticles with fractional charge and exotic exchange statistics,
has inspired decades of condensed matter research. Quantum Hall interferometers enable …

Electronic interferometers using the chiral, one-dimensional (1D) edge channels of the
quantum Hall effect (QHE) can demonstrate a wealth of fundamental phenomena. The …

Anyons are two dimensional particles with fractional exchange statistics that emerge as
elementary excitations of fractional quantum Hall phases. Experimentally, anyonic statistics …

The pairing of electrons is ubiquitous in electronic systems featuring attractive inter–electron
interactions, as exemplified in superconductors. Counterintuitively, it can also be mediated …

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 …

In an all-van der Waals heterostructure, the active layer, gate dielectrics and gate electrodes
are assembled from two-dimensional crystals that have a low density of atomic defects. This …

Quantum point contacts (QPCs) are an essential component in mesoscopic devices. Here,
we study the transmission of quantum Hall edge modes through a gate-defined QPC in …
