Determination of Rashba and Dresselhaus spin-orbit fields
  Determination of Rashba and Dresselhaus spin-orbit interaction strengths in a particular sample remains a challenge even today. In this article we investigate the possibilities of measuring the absolute values of these interaction strengths by calculating persistent charge and spin currents in a mesoscopic ring. Our numerical results can be verified experimentally.
