  • Anisotropic plasmons in a two-dimensional electron gas with spin-orbit interaction 

    Badalyan, S. M.; Matos-Abiague, A.; Vignale, Giovanni, 1957-; Fabian, J. (American Physical Society, 2009)
    Spin-orbit coupling-induced anisotropies of plasmon dynamics are investigated in two- dimensional semiconductor structures. The interplay of the linear Bychkov-Rashba and Dresselhaus spin-orbit interactions drastically ...

  • Beating of Friedel oscillations induced by spin-orbit interaction 

    Badalyan, S. M.; Matos-Abiague, A.; Vignale, Giovanni, 1957-; Fabian, J. (American Physical Society, 2010)
    By exploiting our recently derived exact formula for the Lindhard polarization function in the presence of Bychkov-Rashba (BR) and Dresselhaus (D) spin-orbit interaction (SOI), we show that the interplay of different SOI ...

  • Exchange and correlation effects on plasmon dispersions and Coulomb drag in low-density electron bilayers 

    Badalyan, S. M.; Kim, C. S.; Vignale, Giovanni, 1957-; Senatore, G. (American Physical Society, 2007)
    We investigate the effect of exchange and correlation (XC) on the plasmon spectrum and the Coulomb drag between spatially separated low-density two-dimensional electron layers. We adopt a different approach, which employs ...

  • Exchange and correlation effects on the plasmon dispersions and the Coulomb drag in low-density electron bilayers 

    Badalyan, S. M.; Kim, C. S.; Vignale, Giovanni, 1957-; Senatore, G. (arXiv, 2006)
    We investigate the effect of exchange and correlation (xc) on the plasmon spectrum and the Coulomb drag between spatially separated low-density two-dimensional electron layers. We adopt a new approach, which employs dynamic ...

  • Finite Width and Local Field Corrections to Spin Coulomb Drag in a Quasi-Two-Dimensional Electron Gas 

    Badalyan, S. M.; Kim, C. S.; Vignale, Giovanni, 1957- (American Physical Society, 2008)
    We study the spin Coulomb drag in a quasi-two-dimensional electron gas of finite transverse width, including local field corrections beyond the random phase approximation (RPA). We find that the finite transverse width of ...

  • Spin accumulation from interlayer scattering in semiconductor bilayers 

    Glazov, M. M.; Semina, M. A.; Badalyan, S. M.; Vignale, Giovanni, 1957- (arXiv, 2011)
    Electrons in double-layer semiconductor heterostructures experience two types of spin- orbit interaction: one arises within each layer from the lack of bulk inversion symmetry and/or externally applied electric fields; the ...

  • Spin Hall Drag 

    Badalyan, S. M.; Vignale, Giovanni, 1957- (arXiv, 2009)
    We predict a new effect in electronic bilayers: the {\it Spin Hall Drag}. The effect consists in the generation of spin accumulation across one layer by an electric current along the other layer. It arises from the combined ...

  • Spin Hall Drag in Electronic Bilayers 

    Badalyan, S. M.; Vignale, Giovanni, 1957- (American Physical Society, 2009)
    We predict a new effect in electronic bilayers: spin Hall drag. The effect consists of the generation of spin accumulation across one layer by an electric current along the other layer. It arises from the combined action ...
