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 ...
Spin-orbit effects in nanowire-based wurtzite semiconductor quantum dots
(American Physical Society, 2013-07-03)
We study the effect of the Dresselhaus spin-orbit interaction on the electronic states and spin relaxation rates of cylindrical quantum dots defined on quantum wires having wurtzite lattice structure. The linear and cubic ...
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 ...
Insensitivity of spin dynamics to the orbital angular momentum transferred from twisted light to extended semiconductors
(American Physical Society, 2015-09)
We study the spin dynamics of carriers due to the Rashba interaction in semiconductor quantum disks and wells after excitation with light with orbital angular momentum. We find that although twisted light transfers orbital ...
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 ...
Spin-orbit coupling and electron spin resonance for interacting electrons in carbon nanotubes
(IOP Publishing, 2004-05)
We review the theoretical description of spin-orbit (SO) scattering and electron spin resonance (ESR) in carbon nanotubes. Particular emphasis is laid on the effects of electron-electron interactions. The SO coupling is ...
Half-metal phases in a quantum wire with modulated spin-orbit interaction
(American Physical Society, 2017-11-17)
Spin dynamics of hot excitons in diluted magnetic semiconductors with spin-orbit interaction
(American Institute of Physics, 2019-07-16)
We explore the impact of a Rashba-type spin-orbit interaction in the conduction band on the spin dynamics of hot excitons in diluted magnetic semiconductor quantum wells. In materials with strong spin-orbit coupling, we ...
