Spin-Hall Effect in A Symmetric Quantum Wells by A Random Rashba Field
C. P. Moca, D. C. Marinescu, S. Filip
Changes dopant ion concentrations in the sides of a symmetric quantum well are known to create a random Rashba-type spin-orbit coupling. Here we demonstrate that, as a consequence,…
Density matrix numerical renormalization group for non-Abelian symmetries
A. I. Toth, C. P. Moca, O. Legeza +1
We generalize the spectral sum rule preserving density matrix numerical renormalization group (DM-NRG) method in such a way that it can make use of an arbitrary number of not neces…
Spin-Hall conductivity of a spin-polarized two-dimensional electron gas with Rashba spin-orbit interaction and magnetic impurities
C. P. Moca, D. C. Marinescu
The Kubo formula is used to calculate the spin-Hall conductivity in a spin-polarized two-dimensional electron system with Rashba-type spin-orbit interaction. As in the case of the…
Non-quasiparticle states in CoMnSi evidenced through magnetic tunnel junction spectroscopy measurements
L. Chioncel, Y. Sakuraba, E. Arrigoni +6
We investigate the effects of electronic correlations in the full-Heusler CoMnSi, by combining a theoretical analysis of the spin-resolved density of states with tunneling-cond…
Finite-size Effects in a Two-Dimensional Electron Gas with Rashba Spin-Orbit Interaction
C. P. Moca, D. C. Marinescu
Within the Kubo formalism, we estimate the spin-Hall conductivity in a two-dimensional electron gas with Rashba spin-orbit interaction and study its variation as a function of diso…
Model Hamiltonian parameters for half-metallic ferromagnets NiMnSb and CrO2
A. Yamasaki, L. Chioncel, A. I. Lichtenstein +1
Using the recently developed Nth-order muffin-tin-orbital (NMTO) based downfolding technique we revisit the electronic properties of half-metallic ferromagnets, the semi-Heusler Ni…
