Josephson current through a quantum dot with spin-orbit coupling
arXiv:cond-mat/0609577 · doi:10.1103/PhysRevB.75.085305
Abstract
The equilibrium Josephson current through a nanoscale multi-level quantum dot with Rashba or Dresselhaus spin-orbit coupling $α$ has been computed. The critical current can be drastically modified already by moderate $α$. In the presence of a Zeeman field, Datta-Das-like oscillatory dependencies on $α$ are predicted.
