Slow Excitation Trapping in Quantum Transport with Long-Range Interactions

TL;DR

This paper investigates how long-range interactions affect quantum transport, revealing that they slow excitation trapping contrary to classical expectations, and provides a perturbation theory explanation.

Contribution

It introduces a perturbation theoretical framework to explain the counterintuitive slowing of excitation trapping caused by long-range interactions in quantum transport.

Findings

Long-range interactions slow quantum excitation trapping.

Classical and quantum behaviors differ with long-range interactions.

Perturbation theory explains the slowdown effect.

Abstract

Long-range interactions slow down the excitation trapping in quantum transport processes on a one-dimensional chain with traps at both ends. This is counter intuitive and in contrast to the corresponding classical processes with long-range interactions, which lead to faster excitation trapping. We give a pertubation theoretical explanation of this effect.
