The observation of chiral-induced spin selectivity (CISS) in biological molecules still awaits a full theoretical explanation. In recent Rapid Communication, Varela et al. [Phys. Rev. B 101, 241410(R) (2020)] presented model for electron transport by tunneling the presence spin-orbit interactions. They then claimed that their produces strong asymmetry due to intrinsic atomic strength. As Hamilt...

We compute nuclear spin dependent structure functions using a dynamical model for bound nucleon densities and hence calculate nuclear modifications to asymmetries observed in recent doubly polarised deep inelastic scattering experiments. We conclude that while the individual densities are changed substantially by nuclear effects, the asymmetries themselves are largely insensitive to these chang...

Spin-split superconductors exhibit an electron-hole asymmetric spin-resolved density of states, but the symmetry is restored upon averaging over spin. On other hand, asymmetry appears again in tunneling junctions spin-split with a spin-polarized barrier. As demonstrated recently both theory and experiment, this fact leads to particularly strong thermoelectric effect superconductor-ferromagnet s...

Spin-flip and non-spin-flip mechanisms have been proposed to explain polarization asymmetry in inelastic electron scattering from iron and nickel. A maximum in the asymmetry near 2 eV in iron can occur by both mechanisms. The 300 meV maximum in nickel is unlikely to occur by non-spin-flip transitions. Spin-resolved electron-energy loss spectroscopy has been used to study electron-hole excitatio...

The helicity modification of light polarization which is induced by the gravitational deflection from a classical heavy rotating body, like a star or a planet, is considered. The expression of the helicity asymmetry is derived; this asymmetry signals the gravitationally induced spin transfer from the rotating body to the scattered photons. E-Mail: [email protected]

We consider the sinφ single target-spin asymmetry in deep-inelastic π + inclusive electroproduction off a longitudinally polarized target. We show that at larger transverse momentum of the outgoing hadron the evaluated asymmetry decreases if one takes into account the first order αS perturbative contribution to the cross section, integrated over the azimuthal angle. This leads to good agreement...

Double-spin asymmetries in the cross section of electroproduction of ρ and φ mesons on the proton and deuteron are measured at the HERMES experiment. The photoabsorption asymmetry in exclusive ρ electroproduction on the proton exhibits a positive tendency. This is consistent with theoretical predictions that the exchange of an object with unnatural parity contributes to exclusive ρ electroprodu...

The ratio of Rashba and Dresselhaus spin splittings of the (001)-grown GaAs/AlGaAs quantum wells (QWs), investigated by the spin photocurrent spectra induced by circular photogalvanic effect (CPGE) at inter-band excitation, has been effectively tuned by changing the well width of QWs and by inserting a one-monolayer-thick InAs layer at interfaces of GaAs/AlGaAs QWs. Reflectance difference spect...

We present a leading order (LO) estimate for the longitidinal-transverse spin asymmetry (ALT ) in the nucleon-nucleon polarized Drell-Yan process at RHIC and HERA~ N energies in comparison with ALL and ATT . ALT receives contribution from g1, the transversity distribution h1, and the twist-3 distributions gT and hL. For the twist-3 contribution we use the bag model prediction evolved to a high ...
