Oscillations of 2D Rashba system spin polarization in quantizing magnetic field

TL;DR

This paper investigates how spin polarization oscillates in a 2D electron system with spin-orbit interaction under a quantizing magnetic field, revealing unusually large oscillations due to magneto-electric effects.

Contribution

It introduces a non-equilibrium statistical operator method to analyze spin polarization oscillations in 2D systems with spin-orbit coupling under magnetic fields, highlighting their anomalously large amplitude.

Findings

Spin polarization oscillations become significantly large in quantizing magnetic fields.

The magneto-electric effect influences spin polarization in 2D electron systems.

The method provides a new way to analyze spin dynamics in quantum systems.

Abstract

We apply the method of the non-equilibrium statistical operator in order to describe the magneto-electric effect in 2D electron system with the spin-orbit interaction, and find the polarization of spins of the charge carriers in quantizing magnetic field. We show that, in quantizing magnetic field, the oscillations of the spin polarization become "anomalously" large.
