We develop a theory of charge transport along the quantum Hall edge proximitized by a "dirty" superconductor. Disorder randomizes the Andreev reflection rendering the conductance of a proximitized segment a stochastic quantity with zero average for a sufficiently long segment. We find the statistical distribution of the conductance and its dependence on electron density, magnetic field, and temperature.

  1. Quantum Hall Andreev Conversion in Graphene Nanostructures

    cond-mat.mes-hall 2025-07 conditional novelty 6.0 of 10

    Chiral Andreev conversion at partially transparent graphene-superconductor interfaces is robust, not valley-degenerate, and can show interference oscillations from intervalley scattering at corners.
