This article explores the dynamics and applications of topological phonons in polymers and supramolecular lattices using the Su-Schrieffer-Heeger (SSH) model. It demonstrates that topological boundary modes, robust against defects and thermal fluctuations, can be engineered by alternating strong and weak molecular interactions. These modes exhibit unique vibrational properties localized at boundaries with “heavy” atoms or molecules. The study combines molecular simulations and mathematical models to reveal how these modes can propagate differently compared to traditional phonon modes, paving the way for applications in phonon circuitry, thermal management, and advanced materials. This research bridges the gap between molecular chemistry and condensed matter physics, offering insights into the design of functional molecular systems with tailored topological properties.

In general, if you enjoy reading this kind of scientific news articles, I would also be keen to connect with fellow researchers based on common research interests in materials science, including the possibility to discuss about any potential interest in the Materials Square cloud-based online platform ( www.matsq.com ), designed for streamlining the execution of materials and molecular modelling simulations!
