Anisotropic spin-orbit induced splitting of intersubband spin plasmons
(EDP Sciences, 2013-01)
The anisotropic splitting of intersubband spin plasmons, resulting from spin-orbit coupling, is studied by angle-resolved inelastic light scattering on a [001]-oriented GaAs/AlGaAs quantum well. Confirming theoretical ...
Orbital and spin dynamics of intraband electrons in quantum rings driven by twisted light
(Optical Society of America, 2011-11)
We theoretically investigate the effect that twisted light has on the orbital and spin dynamics of electrons in quantum rings possessing sizable Rashba spin-orbit interaction. The system Hamiltonian for such a strongly ...
Nonmonotonic spin relaxation and decoherence in graphene quantum dots with spin-orbit interactions
(American Physical Society - APSCollege Park, 2014-03)
We investigate the spin relaxation and decoherence in a single-electron graphene quantum dot with Rashba and intrinsic spin-orbit interactions.We derive an effective spin-phonon Hamiltonian via the Schrieffer-Wolff ...
Ultrafast spin dynamics in II-VI diluted magnetic semiconductors with spin-orbit interaction
(American Physical Society, 2015-05)
We study theoretically the ultrafast spin dynamics of II-VI diluted magnetic semiconductors in the presence of spin-orbit interaction. Our goal is to explore the interplay or competition between the exchange sd coupling ...
Phase separation in a spin-orbit-coupled Bose-Einstein condensate
(2014-10-20)
We study a spin-orbit (SO)-coupled hyperfine spin-1 Bose-Einstein condensate (BEC) in a quasi-one-dimensional trap. For an SO-coupled BEC in a one-dimensional box, we show that in the absence of the Rabi term, any nonzero ...
Half-metal phases in a quantum wire with modulated spin-orbit interaction
(American Physical Society, 2017-11)
We propose a spin filter device based on the interplay of a modulated spin-orbit interaction and a uniform external magnetic field acting on a quantum wire. Half-metal phases, where electrons with only a selected spin ...
Spin Hall Effect in Symmetric Wells with Two Subbands
(SPRINGER, 2010)
We investigate the spin Hall conductivity sigma (xy) (z) of a clean 2D electron gas formed in a two-subband well. We determine sigma (xy) (z) as arising from the inter-subband induced spin-orbit (SO) coupling eta (Calsaverini ...
Kondo effect in graphene with Rashba spin-orbit coupling
(American Physical Society, 2014-07)
We study the Kondo screening of a magnetic impurity adsorbed in graphene in the presence of Rashba spin-orbit interaction. The system is described by an effective single-channel Anderson impurity model, which we analyze ...
Spin-orbit effects on two-electron states in nanowhisker double quantum dots
(Elsevier Science, 2009-05)
We investigate theoretically the combined effects of the electron-electron and the Rashba spin-orbit interactions on two electrons confined in quasi-one-dimensional semiconductor double quantum dots. We study both InSb-based ...
NMR spin-spin coupling constants and hyperconjugative interactions
(John Wiley & Sons Inc, 2010-06)
The potential of NMR spin-spin coupling constants as probes to study fine details of electronic molecular structures is briefly discussed in this work through two different examples. A qualitative analysis of the polarization ...
