Long-range-interactions induced ordered structures in deposition processes

TL;DR

This paper introduces a model of particle deposition with dipolar interactions, demonstrating that long-range forces can induce highly ordered structures at low temperatures, affecting the pair correlation and jamming limit.

Contribution

It presents a novel model incorporating long-range dipolar interactions in deposition processes, revealing new ordered structures and phenomenology.

Findings

Ordered structures form at low temperatures due to dipolar interactions

Significant changes in pair correlation functions observed

Variation in jamming limit compared to noninteracting particles

Abstract

We present a new model of sequential adsorption in which the adsorbing particles experience dipolar interactions. We show that in the presence of these long-range interactions, highly ordered structures in the adsorbed layer may be induced at low temperatures. The new phenomenology manifests through significant variations of the pair correlation function and the jamming limit, with respect to the case of noninteracting particles. Our study could be relevant in understanding the adsorption of magnetic colloidal particles in presence of a magnetic field.
