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 ...
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 ...
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 ...
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 ...
Relaxation mechanism for electron spin in the impurity band of n -doped semiconductors
(American Physical Society, 2007-12)
We propose a mechanism to describe spin relaxation in n -doped III-V semiconductors close to the Mott metal-insulator transition. Taking into account the spin-orbit interaction induced spin admixture in the hydrogenic donor ...
Superadiabatic spin-preserving control of a single-spin qubit in a double quantum dot with spin–orbit interaction
(IOP Publishing, 2019-10)
A protocol for controlling the localization of an electron with a fixed projection of spin between two quantum dots in a material with spin-orbit (SO) interaction is studied. Due to SO coupling, the manipulation of the ...
Level structure and spin-orbit effects in quasi-one-dimensional semiconductor nanostructures
(American Physical Society, 2005-12)
We investigate theoretically how the spin-orbit Dresselhaus and Rashba effects influence the electronic structure of quasi-one-dimensional semiconductor quantum dots, similar to those that can be formed inside semiconductor ...
Ballistic spin resonance in multisubband quantum wires
(American Physical Society, 2014-03-25)
Ballistic spin resonance was experimentally observed in a quasi-one-dimensional wire by Frolov et al. [Nature (London) 458, 868 (2009)]. The spin resonance was generated by a combination of an external static magnetic field ...
Symmetries and hybridization in the indirect interaction between magnetic moments in MoS2 nanoflakes
(American Physical Society, 2016-12)
We study the Ruderman-Kittel-Kasuya-Yosida interaction between magnetic impurities embedded in p-doped transition metal dichalcogenide triangular flakes. The role of underlying symmetries is exposed by analyzing the ...
Spin and orbital ordering in bilayer Sr3Cr2 O7
(American Physical Society, 2019-05)
Using maximally localized Wannier functions obtained from density functional theory calculations, we derive an effective Hubbard Hamiltonian for a bilayer of Sr3Cr2O7, the n=2 member of the Ruddlesden-Popper Srn+1CrnO3n+1 ...
