Detecção elétrica de correntes de spin em sistemas nano-estruturados
(Universidade Federal de Santa MariaCentro de Ciências Naturais e Exatas, 2016-12-15)
Spintronics is an emergent research field that seeks a better understanding of the role of electronic spin in solid state physics. Exploring electrons’ charge and spin, significant technological advances might be achieved, ...
Application of the electron localization function of radical systems
(2003)
An application of the topological electron localization function (ELF) analysis of free radical systems is presented. A separation of the ELF function into its α-spin and β-spin contributions has been performed. Methyl and ...
Effect of the Rashba and Dresselhaus spin-splitting terms on the electron g factor in semiconductor quantum wells under applied magnetic fields
(2008-03-01)
We use the Ogg-McCombe Hamiltonian together with the Dresselhaus and Rashba spin-splitting terms to find the g factor of conduction electrons in GaAs-(Ga,Al)As semiconductor quantum wells (QWS) (either symmetric or asymmetric) ...

Towards coherent optical control of a single hole spin: Rabi rotation of a trion conditional on the spin state of the hole
(Pergamon-Elsevier B.V. Ltd, 2009-09-01)
A hole spin is a potential solid-state q-bit, that may be more robust against nuclear spin induced dephasing than an electron spin. Here we propose and demonstrate the sequential preparation, control and detection of a ...

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 ...
