摘要：
The equilibrium Josephson current through a nanoscale multilevel 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.
