TL;DR

This paper analytically investigates how plasmon interactions influence thermally activated transport in disordered quantum wire arrays, revealing a temperature dependence governed by Luttinger liquid parameters.

Contribution

It introduces an analytical model for plasmon-assisted transport in disordered quantum wires, highlighting the impact of strong electron-plasmon interactions on resistance behavior.

Findings

Plasmon interactions qualitatively change temperature dependence of resistance.

High-temperature resistance depends on Luttinger liquid interaction parameter.

Transport mechanism differs from phonon-assisted processes.

Abstract

Phononless plasmon assisted thermally activated transport through a long disordered array of finite length quantum wires is investigated analytically. Generically strong electron plasmon interaction in quantum wires results in a qualitative change of the temperature dependence of thermally activated resistance in comparison to phonon assisted transport. At high temperatures, the thermally activated resistance is determined by the Luttinger liquid interaction parameter of the wires.
