Phys. Rev. B 72, 235305 (2005) [6 pages]Stroboscopic model of transport through a quantum dot with spin-orbit scattering
J. H. Bardarson1, J. Tworzydło2, and C. W. J. Beenakker1 Received 23 August 2005; revised 14 October 2005; published 5 December 2005 We present an open version of the symplectic kicked rotator as a stroboscopic model of electrical conduction through an open ballistic quantum dot with spin-orbit scattering. We demonstrate numerically and analytically that the model reproduces the universal weak localization and weak antilocalization peak in the magnetoconductance, as predicted by random-matrix theory (RMT). We also study the transition from weak localization to weak antilocalization with increasing strength of the spin-orbit scattering, and find agreement with RMT. ©2005 The American Physical Society
