Spin polarization induced by decoherence in a tunneling one-dimensional Rashba model

open access: yesSciPost Physics Core, 2023
Basic questions on the nature of spin polarization in two terminal systems and the way in which decoherence breaks Time-Reversal Symmetry (TRS) are analyzed. We exactly solve several one-dimensional models of tunneling electrons and show the interplay of

Nucleon spin polarization in intermediate-energy heavy-ion collisions

open access: yesPhysics Letters B, 2020
Based on a spin-dependent Boltzmann-Uehling-Uhlenbeck transport model with spin-dependent potentials incorporated using the lattice Hamiltonian method, we have studied the global spin polarization perpendicular to the reaction plane as well as the local ...

Chirality and Spin: A Different Perspective on Enantioselective Interactions

open access: yesCHIMIA, 2018
This review describes a new perspective on the role that electron spin plays in the intermolecular forces between two chiral molecules and between chiral molecules and surfaces. This different role of the spin arises from the chiral induced spin

Spatial separation of spin currents in transition metal dichalcogenides

open access: yesSciPost Physics Core, 2023
We theoretically predict spatial separation of spin-polarized ballistic currents in transition metal dichalcogenides (TMDs) due to trigonal warping.

Spin polarization and Fano–Rashba resonance in nonmagnetic graphene

open access: yesNew Journal of Physics, 2023
We study the symmetry of spin transport in graphene with the Rashba spin–orbit coupling (SOC) and the staggered potential, which can be produced by depositing the graphene on a transition-metal dichalcogenides substrate.

Helical spin texture of surface states in topological superconductors

open access: yesNew Journal of Physics, 2015
Surface states of topological noncentrosymmetric superconductors (NCSs) exhibit intricate helical spin textures, i.e., the spin orientation of the surface quasiparticles is coupled to their momentum.

Coherence Time Extension by Large-Scale Optical Spin Polarization in a Rare-Earth Doped Crystal

open access: yesPhysical Review X, 2020
Optically addressable spins are actively investigated in quantum communication, processing, and sensing. Optical and spin coherence lifetimes, which determine quantum operation fidelity and storage time, are often limited by spin-spin interactions, which

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-polarization after scattering

open access: yesPhysics Open, 2023
This paper deals with the spin-polarization change of an electron beam after elastic scattering with a neutral atom. The first part of the paper is devoted to summarizing the Kessler theory of the elastic scattering of spin-polarized electron beams ...
