Coulomb corrections to the extrinsic spinHall effect of a twodimensional electron gas
Hankiewicz, E. M.; Vignale, Giovanni, 1957 (American Physical Society, 2006)We develop the microscopic theory of the extrinsic spinHall conductivity of a two dimensional electron gas, including skew scattering, sidejump, and Coulomb interaction effects. We find that while the spinHall ... 
Gilbert damping and spin Coulomb drag in a magnetized electron liquid with spinorbit interaction
Hankiewicz, E. M.; Vignale, Giovanni, 1957; Tserkovnyak, Yaroslav (American Physical Society, 2007)We present a microscopic calculation of the Gilbert damping constant for the magnetization of a twodimensional spin polarized electron liquid in the presence of intrinsic spinorbit interaction. First, we show that the ... 
Inhomogeneous Gilbert damping from impurities and electronelectron interactions
Hankiewicz, E. M.; Vignale, Giovanni, 1957; Tserkovnyak, Yaroslav (American Physical Society, 2008)We present a unified theory of magnetic damping in itinerant electron ferromagnets at order q2 including electronelectron interactions and disorder scattering. We show that the Gilbert damping coefficient can be expressed ... 
Phase Diagram of the Spin Hall Effect
Hankiewicz, E. M.; Vignale, Giovanni, 1957 (American Physical Society, 2008)We obtain analytic formulas for the frequencydependent spinHall conductivity of a twodimensional electron gas (2DEG) in the presence of impurities, linear spin orbit Rashba interaction, and external magnetic field ... 
Side jumps in the spin Hall effect: Construction of the Boltzmann collision integral
Culcer, Dimitrie; Hankiewicz, E. M.; Vignale, Giovanni, 1957; Winkler, R. (American Physical Society, 2010)We present a systematic derivation of the sidejump contribution to the spin Hall current in systems without bandstructure spinorbit interactions, focusing on the construction of the collision integral for the Boltzmann ... 
SpinHall effect and spinCoulomb drag in doped semiconductors
Hankiewicz, E. M.; Vignale, Giovanni, 1957 (American Institute of Physics, 2009)In this review, we describe in detail two important spintransport phenomena: the extrinsic spinHall effect (coming from spinorbit interactions between electrons and impurities) and the spinCoulomb drag. The interplay ... 
SpinHall Effect in a [110] GaAs Quantum Well
Hankiewicz, E. M.; Vignale, Giovanni, 1957; Flatte, M. E. (American Physical Society, 2006)A selfconsistent treatment of the spinHall effect requires consideration of the spin orbit coupling and electronimpurity scattering on equal footing. This is done here for the experimentally relevant case of a [110] ... 
Transverse spin diffusion in ferromagnets
Tserkovnyak, Yaroslav; Hankiewicz, E. M.; Vignale, Giovanni, 1957 (American Physical Society, 2009)We discuss the dissipative diffusiontype term of the form m×∇2∂tm in the phenomenological LandauLifshitz equation of ferromagnetic precession, which describes enhanced Gilbert damping of finitemomentum spin waves. This ...
