This is theoretical work lead by Catalina Marinescu, Clemson University, and J. Carlos Egues, Sao Paulo University, with experiments by Pirmin Weigele and Dominik Zumbühl, University of Basel. We have derived a closed-form expression for the weak localization corrections to the magnetoconductivity of a 2D electron system such as a GaAs quantum well with arbitrary Rashba and both linear and cubic Dresselhaus spin-orbit interactions in a perpendicular magnetic field geometry.
