## Description

- description: "Quantum Hall Fabry-Pérot interferometers are sensitive to the properties
    of bulk quasiparticles enclosed by the interferometer loop, with the interference
    phase containing information about both the quasiparticle statistics and the Coulomb-mediated
    bulk-edge coupling. Previous studies have explored the role of the bulk-edge coupling
    in an equilibrium picture where quasiparticles enter and exit the interferometer
    rapidly compared to the timescale over which the interferometer phase is measured.
    Here, we present data from a monolayer graphene quantum Hall interferometer in
    the integer quantum Hall regime at \U0001D708=−1 and \U0001D708=−2. Quantum interference
    shows phase slips associated with the entrance of quasiparticles to the interferometer
    bulk. Tracing the dependence of these phase slips on the magnetic field, we show
    that the equilibration time can become as long as several minutes. We further
    use our multigated geometry to identify two classes of phase slips. The first
    is associated with the addition of a quasiparticle to a bulk “puddle” of quasiparticles
    uniformly coupled to the entire chiral edge state, while the second is associated
    with the addition of a quasiparticle trapped by a defect site that couples predominantly
    to the closest portion of the edge."
