Virgo Detector Characterization and Data Quality: tools
F. Acernese, M. Agathos, A. Ain +491
Detector characterization and data quality studies -- collectively referred to as {\em DetChar} activities in this article -- are paramount to the scientific exploitation of the jo…
Virgo Detector Characterization and Data Quality: results from the O3 run
F. Acernese, M. Agathos, A. Ain +491
The Advanced Virgo detector has contributed with its data to the rapid growth of the number of detected gravitational-wave (GW) signals in the past few years, alongside the two Adv…
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…
Virgo Detector Characterization and Data Quality during the O3 run
F. Acernese, M. Agathos, A. Ain +491
The Advanced Virgo detector has contributed with its data to the rapid growth of the number of detected gravitational-wave signals in the past few years, alongside the two LIGO ins…
The Virgo O3 run and the impact of the environment
F. Acernese, M. Agathos, A. Ain +486
Sources of geophysical noise (such as wind, sea waves and earthquakes) or of anthropogenic noise impact ground-based gravitational-wave interferometric detectors, causing transient…
Measurement and simulation of mechanical and optical properties of sputtered amorphous SiC coatings
G. Favaro, A. Amato, F. Arciprete +15
In this work We report on the extensive characterization of amorphous silicon carbide (a-SiC) coatings prepared by physical deposition methods. We compare the results obtained on t…
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…
Thermodynamic scaling of vibrational dynamics and relaxation
F. Puosi, O. Chulkin, S. Bernini +2
We investigate by thorough Molecular Dynamics simulations the thermodynamic scaling (TS) of a polymer melt. Two distinct models, with strong and weak virial-energy correlations, ar…
Weak links between fast mobility and local structure in molecular and atomic liquids
S. Bernini, F. Puosi, D. Leporini
We investigate by Molecular-Dynamics simulations the fast mobility - the rattling amplitude of the particles temporarily trapped by the cage of the neighbors - in mildly supercoole…
Cage rattling does not correlate with the local geometry in molecular liquids
S. Bernini, F. Puosi, D. Leporini
Molecular-dynamics simulations of a liquid of short linear molecules have been performed to investigate the correlation between the particle dynamics in the cage of the neighbors a…
Direct calculation of the critical Casimir force in a binary fluid
Francesco Puosi, David Lopes Cardozo, Sergio Ciliberto +1
We show that critical Casimir effects can be accessed through direct simulation of a model binary fluid passing through the demixing transition. We work in the semi grand canonical…
Competition of the connectivity with the local and the global order in polymer melts and crystals
S. Bernini, F. Puosi, M. Barucco +1
The competition between the connectivity and the local or global order in model fully-flexible chain molecules is investigated by molecular-dynamics simulations. States with both m…
The kinetic fragility of liquids as manifestation of the elastic softening
F. Puosi, D. Leporini
We show that the fragility , the steepness of the viscosity and relaxation time close to the vitrification, increases with the degree of elastic softening, i.e. the decrease of…
