Abstract

- Quantum oscillations of the spin conductance through regular and chaotic 2D quantum dots under the varying Rashba spin-orbit interaction and at zero magnetic field have been investigated numerically by summing up the spin evolution matrices for classical transmitting trajectories. The Fourier analysis of these oscillations indicates a strong geometry dependence of the power spectra. The spectra for narrow rings are dominated by a single peak as previous analytic result, for regular quantum dots are represented by multiple peaks, and for chaotic quantum dots by quasi-continuum peaks.
