Van der Waals interactions in linear chains with long-range correlated disorder

TL;DR

This paper investigates how van der Waals forces in disordered linear molecular chains are affected by long-range correlations, revealing a complex dependence that can be described analytically.

Contribution

It provides the first theoretical analysis of van der Waals interactions considering long-range correlated disorder in linear chains, with semianalytical expressions derived.

Findings

Interaction energy varies nonmonotonously with disorder correlation length

Analytical expressions for interaction energy in disordered chains are developed

Disorder correlation significantly influences van der Waals forces

Abstract

We present a theoretical study of van der Waals interaction forces in disordered linear molecule chains. We demonstrate that the interaction energy strongly and nonmonotonously depends on the disorder correlation length. Semianalytical expressions for the interaction energy are obtained.
