D. Bazeia, E. Ventura
TL;DR
This paper presents a new coupled torsional and longitudinal model for crystalline polyethylene that accurately describes stable topological twistons, extending previous models that only considered torsional motion.
Contribution
It introduces an extended model coupling torsional and longitudinal degrees of freedom and finds exact solutions for stable topological twistons.
Findings
Exact solutions for stable twistons are found.
The model aligns well with polyethylene's interactions.
It extends previous torsional-only models.
Abstract
We introduce an alternate model to describe twistons in crystalline polyethylene. The model couples torsional and longitudinal degrees of freedom and appears as an extension of a model that describes only the torsional motion. We find exact solutions that describe stable topological twistons, in good agreement with the torsional and longitudinal interactions in polyethylene.
