Transport theory for disordered multiple-band systems: Anomalous Hall effect and anisotropic magnetoresistance
(American Physical Society, 2009)
We present a study of transport in multiple-band noninteracting Fermi metallic systems based on the Keldysh formalism and the self-consistent T-matrix approximation (TMA) taking into account the effects of Berry curvature ...
Spin Hall and spin-diagonal conductivity in the presence of Rashba and Dresselhaus spin-orbit coupling
(American Physical Society, 2004)
We investigate the spin-current linear response conductivity tensor to an electric field in a paramagnetic two-dimensional electron gas with both Rashba and Dresselhaus spin-orbit coupling in the weak scattering regime ...
Anomalous Hall effect in a two-dimensional Dirac band: The link between the Kubo-Streda formula and the semiclassical Boltzmann equation approach RID B-5617-2009
(American Physical Society, 2007)
The anomalous Hall effect (AHE) is a consequence of spin-orbit coupling in a ferromagnetic metal and related primarily to density-matrix response to an electric field that is off-diagonal in band index. For this reason ...
Anomalous Hall effect in a two-dimensional electron gas
(American Physical Society, 2007)
The anomalous Hall effect in a magnetic two-dimensional electron gas with Rashba spin-orbit coupling is studied within the Kubo-Streda formalism in the presence of pointlike potential impurities. We find that all contributions ...
Physical limits of the ballistic and nonballistic spin-field-effect transistor: Spin dynamics in remote-doped structures
(American Physical Society, 2005)
We investigate the spin dynamics and relaxation in remotely doped two dimensional electron systems where the dopants lead to random fluctuations of the Rashba spin-orbit coupling. Due to the resulting random-spin precession, ...
Manifestation of the spin Hall effect through charge-transport in the mesoscopic regime
(American Physical Society, 2004)
We study theoretically the manifestation of the spin Hall effect in a two-dimensional electronic system with Rashba spin-orbit coupling via dc-transport measurements in realistic mesoscopic H-shape structures. The ...
