Semiclassical studies of the influence of spin-orbit interaction on transport through ballistic chaotic quantum dots — Jens Bolte¹ and •Daniel Waltner² — ¹Institut für Theoretische Physik, Universität Ulm, Albert-Einstein-Allee 11, 89081 Ulm, Germany — ²Institut für Theoretische Physik, Universität Regensburg, Universitätsstraße 31, 93040 Regensburg, Germany

The semiclassical justification of the results obtained by Random Matrix Theory for spectral statistics and transport is an important issue of current research in quantum chaos.

By using the Landauer approach and semiclassical methods, we investigate the influence of weak spin-orbit interaction on transport through classically chaotic billiards. By assuming the ergodicity of the combined phase-space dynamics, we are able to reproduce the complete result for the conductivity of the system from the circular symplectic ensemble of Random Matrix Theory and to explain weak localization and weak antilocalization.
