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…
Non-Reciprocal Supercurrents in a Field-Free Graphene Josephson Triode
John Chiles, Ethan G. Arnault, Chun-Chia Chen +6
Superconducting diodes are proposed non-reciprocal circuit elements that should exhibit non-dissipative transport in one direction while being resistive in the opposite direction.…
Loss and decoherence at the quantum Hall - superconductor interface
Lingfei Zhao, Zubair Iftikhar, Trevyn F. Q. Larson +5
We perform a systematic study of Andreev conversion at the interface between a superconductor and graphene in the quantum Hall (QH) regime. We find that the probability of Andreev…
Phase dynamics in an AC driven multiterminal Josephson junction analogue
François Amet, Sara Idris, Aeron McConnell +2
In the presence of an AC drive, multiterminal Josephson junctions exhibit the inverse AC Josephson effect, where the oscillations of the superconducting phase of each junction can…
Graphene-based quantum Hall interferometer with self-aligned side gates
Lingfei Zhao, Ethan G. Arnault, Trevyn F. Q. Larson +7
The vanishing band gap of graphene has long presented challenges for making high-quality quantum point contacts (QPCs) -- the partially transparent p-n interfaces introduced by con…
Dynamical Stabilization of Multiplet Supercurrents in Multi-terminal Josephson Junctions
Ethan G. Arnault, Sara Idris, Aeron McConnell +6
The dynamical properties of multi-terminal Josephson junctions have recently attracted interest, driven by the promise of new insights into synthetic topological phases of matter a…
