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…
Scaling properties of noise-induced switching in a bistable tunnel diode circuit
Stephen W. Teitsworth, Matthew E. Olson, Yuriy Bomze
Noise-induced switching between coexisting metastable states occurs in a wide range of far-from-equilibrium systems including micro-mechanical oscillators, epidemiological and clim…
Ballistic graphene Josephson junctions from the short to the long regime
I. V. Borzenets, F. Amet, C. T. Ke +9
We investigate the critical current, , of ballistic Josephson junctions made of encapsulated graphene/boron-nitride heterostructures. We observe a crossover from the short to…
Critical current scaling in long diffusive graphene-based Josephson junctions
Chung-Ting Ke, Ivan V. Borzenets, Anne W. Draelos +8
We present transport measurements on long diffusive graphene-based Josephson junctions. Several junctions are made on a single-domain crystal of CVD graphene and feature the same c…
Phonon bottleneck in graphene-based Josephson junctions at millikelvin temperatures
I. V. Borzenets, U. C. Coskun, H. T. Mebrahtu +3
We examine the nature of the transitions between the normal and the superconducting branches of superconductor-graphene-superconductor Josephson junctions. We attribute the hystere…
Observation of Majorana Quantum Critical Behavior in a Resonant Level Coupled to a Dissipative Environment
H. T. Mebrahtu, I. V. Borzenets, H. Zheng +5
We investigate experimentally an exotic state of electronic matter obtained by fine-tuning to a quantum critical point (QCP), realized in a spin-polarized resonant level coupled to…
