Surface viscosity in simple liquids
Paolo Malgaretti, Ubaldo Bafile, Renzo Vallauri +2
The response of Newtonian liquids to small perturbations is usually considered to be fully described by homogeneous transport coefficients like shear and dilatational viscosity. Ho…
Role of the single-particle dynamics in the transverse current autocorrelation function of a liquid metal
Eleonora Guarini, Ubaldo Bafile, Daniele Colognesi +6
A very recent simulation study of the transverse current autocorrelation of the Lennard-Jones fluid revealed, as expected, that this function can be perfectly described within the…
Ice phonon spectra and Bayes inference: a gateway to a new understanding of terahertz sound propagation in water
Alessio De Francesco, Luisa Scaccia, Ferdinando Formisano +5
Understanding how molecules engage in collective motions in a liquid where a network of bonds exists has both fundamental and applied relevance. On the one hand, it can elucidate t…
Onset of two collective excitations in the transverse dynamics of a simple fluid
Eleonora Guarini, Martin Neumann, Alessio De Francesco +5
A thorough analysis of the transverse current autocorrelation function obtained by molecular dynamics simulations of a dense Lennard-Jones fluid reveals that even such a simple sys…
Modeling neutron and X-ray scattering by liquids
Wouter Montfrooij, Ubaldo Bafile, Eleonora Guarini
We review exact formalisms for describing the dynamics of liquids in terms of static parameters. We discuss how these formalisms are prone to suffer from imposing restrictions that…
A Bayesian analysis of neutron spin echo data on polymer coated gold nanoparticles in aqueous solutions
Alessio De Francesco, Luisa Scaccia, R. Bruce Lennox +4
We present a neutron spin echo study (NSE) of the nanosecond dynamics of polyethylene glycol (PEG) functionalised nanosized gold particles dissolved in DO at two temperatures a…
