Quantum coherence and control is foundational to the science and engineering of quantum
systems,. In van der Waals materials, the collective coherent behaviour of carriers has been …

We develop the theory of an Andreev junction, which provides a method to probe the
intrinsic topology of the Fermi sea of a two-dimensional electron gas (2DEG). An Andreev …

Hexagonal boron nitride is a large band gap layered crystal, frequently incorporated in van
der Waals heterostructures as an insulating or tunnel barrier. Localised states with energies …

We simulate a hybrid superconductor-graphene device in the quantum Hall regime to
identify the origin of downstream resistance oscillations in a recent experiment [Zhao et. al …

Quantum dots have sharply defined energy levels, which can be used for high resolution
energy spectroscopy when integrated in tunneling circuitry. Here we report dot-assisted …

We report on a ballistic and fully tunable Josephson-junction system consisting of two
parallel ribbons of graphene in contact with superconducting molybdenum-rhenium. By …

Short ballistic graphene Josephson junctions sustain superconducting current with a non-
sinusoidal current-phase relation up to a critical current threshold. The current-phase …

We demonstrate that the mode number of Andreev bound states in bilayer graphene
Josephson junctions can be modulated by controlling the superconducting coherence …

We study nonequilibrium Andreev resonances in a voltage-biased graphene three-terminal
Josephson junction (JJ). We observe periodic oscillations of resistance with maxima at …

Despite the structural simplicity of graphene, its mechanical and electronic remarkable
properties make this material a credible starting point for new technologies across a wide …
