González/titolo:Neutron scattering and ab initio simulation: Two essential and inseparable tools for studying liquids dynamics. The case of shear waves in silver/editore:/anno:2021
Assessing the experimental visibility of shear-wave excitations has recently become a hot topic in the field of liquids dynamics. Experimental investigations, mostly focused on liquid metals, have reported contrasting results in different systems. In

We discuss the general theory of time correlation functions and their spectra as given by Mori and Zwanzig, and present an alternative formulation based on recurrence relations of new basis vectors in the Hilbert space of the analyzed property. We al

Comment on 'An effective fitting scheme for the dynamic structure of pure liquids'
Autor: U. Bafile (1), E. Guarini (2), F. Barocchi (2)

Comment The occurrence of a propagation gap in the acoustic excitations of a liquid is excluded by Wax and Bryk (2013 J. Phys.: Condens. Matter 25 325104). The requirement of a finite second frequency moment for the dynamic structure factor is used t

Pressure and temperature variation of the depolarized light scattering spectra of the fragile glass-former liquid salol
Autor: F. Barocchi, G. Pratesi, A. Bellosi
Publikováno v: The European Physical Journal B. 18:283-287
The pressure and temperature dependences of the depolarized light scattering spectra of salol have been measured at isobaric condition P = 1 bar for T between 328 and 393 K, and at isothermal condition T = 343 K for P between 1 and 625 bar, i.e. outs

Long-range interactions in insulating fluids probed by SANS
Autor: G. Casanova, Renato Magli, Ferdinando Formisano, Eleonora Guarini, Ubaldo Bafile, F. Barocchi
Publikováno v: Journal of Applied Crystallography. 33:763-766
The study of the microscopic interaction law represents a centraltopic in the physics of the fluid state of matter. Particular interest has been devoted in the past decades to the long-range part of the interatomic force. We review here some recent r

The knowledge about the microscopic dynamics of a fluid at equilibrium has, in the years, been increased by neutron or X-rays spectroscopic investigations of liquid metals. Indeed, these are the emblem of "simple fluids", notwithstanding basic differ
