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 ...
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) ...

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 ...
Ferromagnetic fluctuations in the Rashba-Hubbard model
(American Physical Society, 2020-05)
We study the occurrence and the origin of ferromagnetic fluctuations in the longitudinal spin susceptibility of the t-t′-Rashba-Hubbard model on the square lattice. The combined effect of the second-neighbor hopping t′ and ...
Influence of Rashba spin-orbit coupling on the 0-π transition and Kondo temperature in one-dimensional superconductors
(American Physical Society, 2019-12)
Using the framework of the density-matrix renormalization group (DMRG), we study a quantum dot coupled to a superconducting nanowire with strong Rashba spin-orbit coupling. Regarding the singlet-to-doublet "0-π" transition ...
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 ...
