Josephson current through a quantum dot with spin-orbit coupling

Abstract

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