Spin transmission through quantum dots with strong spin-orbit interaction

Chang, CH ; Mal'shukov, AG and Chao, Koung-An LU (2004) In Physics Letters. Section A: General, Atomic and Solid State Physics 326(5-6). p.436-441
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.
