  "abstract": "We demonstrate that the phenomenon of the current confinement along the graphene n-p junctions at high magnetic fields can be used to form an Aharonov-Bohm interferometer. The interference system exploits a closed n-p junction that can be induced by a floating gate within the sample and coupling of the junction currents with the edge currents in the quantum Hall regime. Operation of the device requires current splitting at the edge -- n-p junction contacts whichis found for armchair ribbons at low Fermi energy.",
