Spin transistor action from Onsager reciprocity and SU(2) gauge theory
I. Adagideli, V. Lutsker, M. Scheid +2
We construct a local gauge transformation to show how, in confined systems, a generic, weak nonhomogeneous SU(2) spin-orbit Hamiltonian reduces to two U(1) Hamiltonians for spinles…
Geometric Correlations and Breakdown of Mesoscopic Universality in Spin Transport
I. Adagideli, Ph. Jacquod, M. Scheid +3
We construct a unified semiclassical theory of charge and spin transport in chaotic ballistic and disordered diffusive mesoscopic systems with spin-orbit interaction. Neglecting dy…
Spin-Orbit Based Coherent Spin Ratchets
Matthias Scheid, Dario Bercioux, Klaus Richter
The concept of ratchets, driven asymmetric periodic structures giving rise to directed particle flow, has recently been generalized to a quantum ratchet mechanism for spin currents…
Spin Accumulation in Diffusive Conductors with Rashba and Dresselhaus Spin-Orbit Interaction
Mathias Duckheim, Daniel Loss, Matthias Scheid +3
We calculate the electrically induced spin accumulation in diffusive systems due to both Rashba (with strength and Dresselhaus (with strength spin-orbit interaction. Usin…
Resonant tunneling-based spin ratchets
Matthias Scheid, Andreas Lassl, Klaus Richter
We outline a generic ratchet mechanism for creating directed spin-polarized currents in ac-driven double well or double dot structures by employing resonant spin transfer through t…
Anisotropic universal conductance fluctuations in disordered quantum wires with Rashba and Dresselhaus spin-orbit interaction and applied in-plane magnetic field
Matthias Scheid, Inanc Adagideli, Junsaku Nitta +1
We investigate the transport properties of narrow quantum wires realized in disordered two-dimensional electron gases in the presence of k-linear Rashba and Dresselhaus spin-orbit…
