The spin-orbit interaction as a source of new spectral and transport properties in quasi-one-dimensional systems

TL;DR

This paper provides an exact theoretical analysis of how spin-orbit interaction influences the band structure and transport properties in long quasi-one-dimensional electron systems, revealing unique effects absent in higher dimensions.

Contribution

It introduces a precise theoretical framework for understanding spin-orbit effects in quasi-one-dimensional systems, highlighting phenomena not observable in higher-dimensional counterparts.

Findings

Spin-orbit interaction modifies the band structure uniquely in quasi-1D systems.

New spectral features emerge due to SO interaction in these systems.

Transport properties are significantly affected by SO effects at low temperatures.

Abstract

We present an exact theoretical study of the effect of the spin-orbit (SO) interaction on the band structure and low temperature transport in long quasi-one-dimensional electron systems patterned in two-dimensional electron gases in zero and weak magnetic fields. We reveal the manifestations of the SO interaction which cannot in principle be observed in higher dimensional systems.
