Josephson current through a quantum dot with spin-orbit coupling

Mesoscale and Nanoscale Physics 2007-05-23 v2 Superconductivity

Abstract

The equilibrium Josephson current through a nanoscale multi-level quantum dot with Rashba or Dresselhaus spin-orbit coupling α\alpha has been computed. The critical current can be drastically modified already by moderate α\alpha. In the presence of a Zeeman field, Datta-Das-like oscillatory dependencies on α\alpha are predicted.
