Plastic ridge formation in a compressed thin amorphous film
Gianfranco Cordella, Francesco Puosi, Antonio Tripodo +2
We demonstrate that surface morphogenesis in compressed thin films may result from spatially correlated plastic activity. A soft glassy film strongly adhering to a smooth and rigid…
Mutual Information in Molecular and Macromolecular Systems
Antonio Tripodo, Francesco Puosi, Marco Malvaldi +1
The relaxation properties of viscous liquids close to their glass transition (GT) have been widely characterised by the statistical tool of time correlation functions. However, the…
Open and anisotropic soft regions in a model polymer glass
Carlo Andrea Massa, Francesco Puosi, Antonio Tripodo +1
The vibrational dynamics of a model polymer glass is studied by Molecular Dynamics simulations. The focus is on the "soft" monomers with high participation to the lower-frequency v…
Johari-Goldstein heterogeneous dynamics in a model polymer
Francesco Puosi, Antonio Tripodo, Marco Malvaldi +1
The heterogeneous character of the Johari-Goldstein (JG) relaxation is evidenced by molecular-dynamics simulation of a model polymer system. A double-peaked evolution of dynamic he…
Non-local cooperative atomic motions that govern dissipation in amorphous tantala unveiled by dynamical mechanical spectroscopy
Francesco Puosi, Francesco Fidecaro, Simone Capaccioli +2
The mechanisms governing mechanical dissipation in amorphous tantala are studied at microscopic scale via Molecular Dynamics simulations, namely by mechanical spectroscopy in a wid…
Fast Vibrational Modes and Slow Heterogeneous Dynamics in Polymers and Viscous Liquids
Francesco Puosi, Antonio Tripodo, Dino Leporini
Many systems, including polymers and molecular liquids, when adequately cooled and/or compressed, solidify into a disordered solid, i.e., a glass. The~transition is not abrupt, fea…
