Noise-induced stabilization of dynamical states with broken time-reversal symmetry
Trevyn F. Q. Larson, Lingfei Zhao, Ethan G. Arnault +7
Under a high frequency drive, Josephson junctions demonstrate "Shapiro steps" of quantized voltage. These are dynamically stabilized states, in which the phase across the junction…
Overdamped Phase Diffusion in hBN Encapsulated Graphene Josephson Junctions
J. Tang, M. T. Wei, A. Sharma +7
We investigate the zero-bias behavior of Josephson junctions made of encapsulated graphene boron nitride heterostructures in the long ballistic junction regime. For temperatures do…
Zero-bias crossings and peculiar Shapiro maps in graphene Josephson junctions
T. F. Q. Larson, L. Zhao, E. G. Arnault +7
The AC Josephson effect manifests itself in the form of "Shapiro steps" of quantized voltage in Josephson junctions subject to RF radiation. This effect presents an early example o…
Anomalous Phase Dynamics of Driven Graphene Josephson Junctions
S. S. Kalantre, F. Yu, M. T. Wei +5
Josephson junctions with weak-links of exotic materials allow the elucidation of the Josephson effect in previously unexplored regimes. Further, such devices offer a direct probe o…
2-periodic magnetic interference in ballistic graphene Josephson junctions
C. T. Ke, A. W. Draelos, A. Seredinski +11
We investigate supercurrent interference patterns measured as a function of magnetic field in ballistic graphene Josephson junctions. At high doping, the expected -periodic…
Chiral Quasiparticle Tunneling Between Quantum Hall Edges in Proximity with a Superconductor
M. T. Wei, A. W. Draelos, A. Seredinski +10
We study a two-terminal graphene Josephson junction with contacts shaped to form a narrow constriction, less than 100nm in length. The contacts are made from type II superconductin…
