Time-dependent current-density functional theory for the friction of ions in an interacting electron gas
V. U. Nazarov, J. M. Pitarke, Y. Takada +2
Due to the strongly nonlocal nature of the {\em scalar} exchange and correlation (xc) kernel of the time-dependent density-functional theory (TDDFT), t…
On the "Causality Paradox" of Time-Dependent Density Functional Theory
G. Vignale
I show that the so-called causality paradox of time-dependent density functional theory arises from an incorrect formulation of the variational principle for the time evolution of…
"Phase Diagram" of the Spin Hall Effect
E. M. Hankiewicz, G. Vignale
We obtain analytic formulas for the frequency-dependent spin-Hall conductivity of a two-dimensional electron gas (2DEG) in the presence of impurities, linear spin-orbit Rashba inte…
Spin Coulomb drag beyond the random phase approximation
S. M. Badalyan, G. Vignale, C. S. Kim
We study the spin Coulomb drag in a quasi-two-dimensional electron gas beyond the random phase approximation (RPA). We find that the finite transverse width of the electron gas cau…
Spin-Hall effect in a [110] quantum well
E. M. Hankiewicz, G. Vignale, M. Flatte
A self-consistent treatment of the spin-Hall effect requires consideration of the spin-orbit coupling and electron-impurity scattering on equal footing. This is done here for the e…
