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…
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…
