Abstract
Despite the importance of Poisson's ratio in materials science and engineering, its connection to molecular dynamics and relaxation processes in glass-forming systems remains unclear. The existence of such connection made the family of metallic glasses in our previous study [K.L. Ngai et al. J. Chem. Phys. 140 (2014) 044511], where it was also justified by molecular dynamics simulation, physics of glass-forming materials, and theoretical considerations. Here we extend the consideration to molecular glass-formers and amorphous polymers, and demonstrate that the Poisson's ratio correlates with several microscopic dynamic properties, and explained theoretically in exactly the same way as given in our previous publication.
