Nonreciprocal charge transport and subharmonic structure in voltage-biased Josephson diodes
A. Zazunov, J. Rech, T. Jonckheere +3
We study charge transport in voltage-biased single-channel junctions involving helical superconductors with finite Cooper pair momentum. For a Josephson junction, the equilibrium c…
Approaching ideal rectification in superconducting diodes through multiple Andreev reflections
A. Zazunov, J. Rech, T. Jonckheere +3
We analyze the rectification properties of voltage-biased Josephson junctions exhibiting the superconducting diode effect. Taking into account multiple Andreev reflection (MAR) pro…
Low-energy theory of transport in Majorana wire junctions
A. Zazunov, R. Egger, A. Levy Yeyati
We formulate and apply a low-energy transport theory for hybrid quantum devices containing junctions of topological superconductor (TS) wires and conventional normal (N) or superco…
Anomalous Josephson current through a spin-orbit coupled quantum dot
A. Zazunov, R. Egger, T. Jonckheere +1
For a general model of a mesoscopic multi-level quantum dot, we determine the necessary conditions for the existence of an anomalous Josephson current with spontaneously broken tim…
Critical Josephson current through a bistable single-molecule junction
Andreas Schulz, Alex Zazunov, Reinhold Egger
We compute the critical Josephson current through a single-molecule junction. As a model for a molecule with a bistable conformational degree of freedom, we study an interacting si…
Superconducting non-equilibrium transport through a weakly interacting quantum dot
L. Dell'Anna, A. Zazunov, R. Egger
We study the out-of-equilibrium current through an interacting quantum dot modelled as an Anderson impurity contacted by two BCS superconductors held at fixed voltage bias. In orde…
