Rashba effect on finite temperature magnetotransport in a dissipative quantum dot transistor with electronic and polaronic interactions

open access: yesScientific Reports, 2023
The Rashba spin–orbit coupling induced quantum transport through a quantum dot embedded in a two-arm quantum loop of a quantum dot transistor is studied at finite temperature in the presence of electron–phonon and Hubbard interactions, an external ...

Spin-orbit-coupling induced electron-spin polarization in magnetically and electrically confined semiconductor microstructure

open access: yesResults in Physics, 2021
We theoretically investigate spin polarization for electrons in magnetically and electrically confined semiconductor microstructure, which is constructed by patterning a ferromagnetic stripe and a Schottky-metal stripe on top and bottom of GaAs/AlxGa1 ...

Spin Polarization of Injected Electrons

open access: yesScience, 2002
LaBella et al . ([1][1]) claimed 92% spin polarization for electrons injected into gallium arsenide [GaAs(110)] from a Ni scanning tunneling microscope (STM) tip, which, they asserted, emitted 100% spin-polarized electrons. Such a claim, if substantiated, would constitute a development of great importance for the emerging field of spintronics: It would

Dynamics of Spin Relaxation near the Edge of Two-Dimensional Electron Gas

open access: yes, 2004
We report calculations of spin relaxation dynamics of two-dimensional electron gas with spin-orbit interaction at the edge region. It is found that the relaxation of spin polarization near the edge is more slow than relaxation in the bulk.

Current induced local spin polarization due to the spin-orbit coupling in a two dimensional narrow strip

open access: yes, 2005
The current induced local spin polarization due to weak Rashba spin-orbit coupling in narrow strip is studied. In the presence of longitudinal charge current, local spin polarizations appear in the sample. The spin polarization perpendicular to the plane

Spin polarization and chiral symmetry breaking at finite density [PDF]

open access: yes, 2006
We investigate the possibility of the spin polarization of quark matter at zero temperature and moderate baryon density.The Nambu-Jona-Lasinio (NJL) model including interactions in vector and axial-vector channel (coupling constant $G_2$) as well as ...

Spin-polarized spin excitation spectroscopy

open access: yesNew Journal of Physics, 2010
We report on the spin dependence of elastic and inelastic electron tunneling through transition metal atoms. Mn, Fe and Cu atoms were deposited onto a monolayer of Cu2N on Cu(100) and individually addressed with the probe tip of a scanning tunneling microscope.

A novel broad-band neutron spin filter based on dynamically polarized protons using photo-excited triplet states [PDF]

open access: yesEPJ Web of Conferences, 2019
The use of polarized protons as a broad-band neutron spin filter is an attractive alternative to the well-established neutron polarization techniques, namely polarized 3He gas and super mirrors, since the spin-dependent neutron proton scattering cross ...

Spin polarization decay in spin-1/2 and spin-3/2 systems

open access: yes, 2007
We present a general unifying theory for spin polarization decay due to the interplay of spin precession and momentum scattering that is applicable to both spin-1/2 electrons and spin-3/2 holes.
