چکیده
It is well known that electron interactions in disordered systems lead to quantum corrections conductivity at low temperatures. This paper devoted the investigation of such context spin Hall effect. In Rashba model conductivity, an incoming scatters off Friedel's oscillations density a two-dimensional gas created by impurity resulting two interfering paths. The authors derive kinetic equation captures these processes, which applicable both diffusive and ballistic transport regimes. They also discuss frequency dependence conductivity.

Spin-Hall conductivity in a two-dimensional Rashba electron gas
Spin-Hall conductivity and Pauli susceptibility of 2D electron gas with Rashba spin-orbital interaction is studied theoretically in the semiclassical limit kFl 1. Static spin-Hall conductivity is shown to be zero for any nonvanishing disorder strength in the general case of the momentum-dependent Rashba velocity p and nonparabolic spectrum p . This result is derived both by an explicit diagramm...
متن کاملUniversality of the Hall conductivity in Interacting electron systems
We prove the quantization of the Hall conductivity for general weakly interacting gapped fermionic systems on two-dimensional periodic lattices. The proof is based on fermionic cluster expansion techniques combined with lattice Ward identities, and on a reconstruction theorem that allows us to compute the Kubo conductivity as the analytic continuation of its imaginary time counterpart.

متن کاملSpin-Hall conductivity of a spin-polarized two-dimensional electron gas with Rashba spin-orbit interaction and magnetic impurities
Abstract The Kubo formula is used to calculate the spin-Hall conductivity σsH in a spin-polarized twodimensional electron system with Rashba-type spin-orbit interaction. As in the case of the unpolarized electron system, σsH is entirely determined by states at the Fermi level, a property that maintains in the presence of magnetic impurities. In the clean limit, the spin-Hall conductivity decrea...
متن کاملSpin-Hall effect in two-dimensional electron systems with Rashba spin-orbit coupling and disorder.
Using the four-terminal Landauer-Bu ttiker formula and Green's function approach, we calculate numerically the spin-Hall conductance in a two-dimensional junction system with the Rashba spin-orbit (SO) coupling and disorder. We find that the spin-Hall conductance can be much greater or smaller than the universal value e/8pi, depending on the magnitude of the SO coupling, the electron Fermi ener...
متن کاملInverse spin Hall effect and anomalous Hall effect in a two-dimensional electron gas
We study the coupled dynamics of spin and charge currents in a two-dimensional electron gas in the transport diffusive regime. For systems with inversion symmetry there are established relations between the spin Hall effect, the anomalous Hall effect and the inverse spin Hall effect. However, in two-dimensional electron gases of semiconductors like GaAs, inversion symmetry is broken so that the...
