Strongly interacting, dynamically disordered and with no small parameter, liquids took a
theoretical status between gases and solids with the historical tradition of hydrodynamic …

The experimental results relevant for the understanding of the microscopic dynamics in
liquid metals are reviewed, with special regard to the ones achieved in the last two decades …

We predict the properties of the propagating and nonpropagating vibrational modes in
amorphous silica (a-SiO 2) and amorphous silicon (a-Si) and, from them, thermal …

We compare the atomic dynamics of the glass to that of the relevant crystal. In the spectra of
inelastic scattering, the boson peak of the glass appears higher than the transverse acoustic …

We measured the density of vibrational states (DOS) and the specific heat of various glassy
and crystalline polymorphs of SiO 2. The typical (ambient) glass shows a well-known excess …

The propagation and damping of the acoustic excitations in vitreous silica is measured at
terahertz frequencies using inelastic x-ray scattering. The apparent sound velocity shows a …

Of the three basic states of matter, liquid is perhaps the most complex. While its flow
properties are described by fluid mechanics, its thermodynamic properties are often …

The phonon spectra of solids, described through the measurable vibrational density of states
(VDOS), provide a wealth of information about the underlying atomic structure and bonding …

High-resolution, inelastic x-ray scattering measurements of the dynamic structure factor S (Q,
ω) of liquid water have been performed for wave vectors Q between 4 and 30 nm− 1 in …

Joint inelastic neutron and x-ray scattering measurements have been performed on heavy
water across the melting point. The spectra bear clear evidence of low-and high-frequency …
