Localisation versus self-trapping: Polaron formation in the Anderson-Holstein model

TL;DR

This paper investigates how disorder affects polaron formation in electron-phonon systems, comparing localization phenomena with self-trapping mechanisms.

Contribution

It provides a comparative analysis of localization and self-trapping in the Anderson-Holstein model, highlighting their interplay in disordered systems.

Findings

Disorder influences polaron size and formation

Localization and self-trapping regimes are interconnected

Disorder enhances polaron trapping in certain regimes

Abstract

We discuss polaron formation in disordered electron-phonon systems.
