Coherent beam splitting of flying electrons driven by a surface acoustic wave
R. Ito, S. Takada, A. Ludwig +3
We develop a coherent beam splitter for single electrons driven through two tunnel-coupled quantum wires by surface acoustic waves (SAWs). The output current through each wire osci…
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…
Mesoscopic phase behavior in a quantum dot around crossover between single-level and multilevel transport regimes
S. Takada, M. Yamamoto, C. Bäuerle +3
The transmission phase across a quantum dot (QD) is expected to show mesoscopic behavior, where the appearance of a phase lapse between Coulomb peaks (CPs) as a function of the gat…
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…
Supercurrent in the quantum Hall regime
Francois Amet, Chung Ting Ke, Ivan V. Borzenets +8
A novel promising route for creating topological states and excitations is to combine superconductivity and the quantum Hall (QH) effect. Despite this potential, signatures of supe…
