Dephasing from interactions and spin disorder

TL;DR

This paper investigates how electron dephasing rates are affected by interactions and spin disorder, showing that dephasing saturates at zero temperature in 2D systems with spin-orbit disorder, aligning with experimental observations.

Contribution

It provides a self-consistent diagrammatic calculation demonstrating dephasing rate saturation at zero temperature due to spin-orbit disorder in 2D.

Findings

Dephasing rate saturates at zero temperature in 2D with spin-orbit disorder.

Theoretical results agree with experimental data.

Interactions and spin disorder jointly influence electron coherence.

Abstract

We calculate the dephasing rate of the electrons in the presence of interactions and elastic spin disorder scattering. In the frame of a self-consistent diagrammatic treatment, we obtain saturation of the dephasing rate in the limit of zero temperature for spin-orbit disorder in 2 dimensions. This result is in agreement with relevant experiments.
