Suppression of spin-orbit effects in 1D system

TL;DR

This paper demonstrates the suppression of spin-orbit effects like spin polarization and spin currents in a one-dimensional system under static electric fields, with exceptions when magnetic interactions are considered.

Contribution

It shows that spin effects are absent in 1D systems with arbitrary spin-orbit interaction unless magnetic field interactions are included.

Findings

Spin effects are suppressed in 1D systems under static electric fields.

Magnetic field interactions can induce spin effects in these systems.

The absence of spin effects holds for arbitrary spin-orbit interaction forms.

Abstract

We report the absence of spin effects such as spin-galvanic effect, spin polarization and spin current under static electric field and inter-spin-subband absorption in 1D system with spin-orbit interaction of arbitrary form. It was also shown that the accounting for the direct interaction of electron spin with magnetic field violates this statement.
