Abstract
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 anti-localization peak in the magnetoconductance, as predicted by random-matrix theory (RMT). We also study the transition from weak localization to weak anti-localization with increasing strength of the spin-orbit scattering, and find agreement with RMT.
