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

In the last decades, the steady improvement of instrumental performance in research and in particular in the field of spectroscopy made available an enormous amount of new data on a variety of physical systems. While in the early years, a merely phen

In this work we describe a Bayesian approach to the analysis of Neutron Brillouin Scattering (NBS) data. Specifically, when dealing with spectra related to liquids and disordered systems, which are typically characterized by a poor definition of the

Methanol is the simplest molecule containing a polar hydroxyl group and a non-polar methyl group, thus offering the possibility of studying the properties of small amphiphile systems in aqueous environments, as well as self-assembly phenomena. As for

The extraction of physical quantitative information from inelastic Brillouin neutron scattering data is often a challenging task, especially when dealing with specific samples or anytime the scattering signal is very weak. These limiting conditions t

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
