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 polarization in the Hubbard model with Rashba spin-orbit coupling on a ladder
(American Physical Society, 2013-07)
The competition between on-site Coulomb repulsion and Rashba spin-orbit coupling (RSOC) is studied on two-leg ladders by numerical techniques. By studying persistent currents in closed rings by exact diagonalization, it ...
Rashba coupling in quantum dots: An exact solution
(American Physical Society, 2004-09)
We present an analytic solution to one-particle Schrödinger equation for an electron in a quantum dot with hard-wall confining potential in the presence of both magnetic field and spin-orbit coupling. Wave-functions, energy ...
Longitudinal optical and spin Hall conductivities of Rashba conducting strips coupled to ferromagnetic and antiferromagnetic layers
(American Physical Society, 2017-01)
A system composed of a conducting planar strip with Rashba spin-orbit coupling (RSOC), magnetically coupled to a layer of localized magnetic moments, at equilibrium, is studied within a microscopic Hamiltonian with numerical ...
Transporte dependente de spin em nanofios semicondutores controlado via interação spin-órbita
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2019-04-26)
This work was dedicated to the theoretical study of semiconductor nanostructures aimed at the implementation of spin dependent electronic transport. The objective was to study the electron transport properties considering ...
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 ...
Rashba spin-orbit interaction in a superlattice of quantum wires
(AMER PHYSICAL SOCCOLLEGE PK, 2012)
In this work, we study the effects of a longitudinal periodic potential on a parabolic quantum wire defined in a two-dimensional electron gas with Rashba spin-orbit interaction. For an infinite wire superlattice we find, ...
Supersolid-like states in a two-dimensional trapped spin-orbit-coupled spin-1 condensate
(2021-06-01)
We study supersolid-like states in a quasi-two-dimensional trapped Rashba and Dresselhaus spin-orbit (SO) coupled spin-1 condensate. For small strengths of SO coupling γ (γ ≲ 0.75), in the ferromagnetic phase, circularly-symmetric ...
