Raman, Brillouin light, and x-ray scattering measurements have been carried out to
characterize the low-frequency vibrational dynamics of the SiO 2 glass as function of its …

Vitreous GeO 2⁠, one of the main prototypes of strong glasses, was densified at several
pressures up to 6 GPa, achieving more than 20% of densification. The density dependence …

Inelastic light-scattering spectra of normal and permanently densified B 2 O 3 glasses were
investigated over the frequency range between 6 and 1600 cm-1. Densification from 1826 to …

Low-temperature experiments of Raman scattering and heat capacity have been performed
in a B2O3 glass, pressure quenched from 1200° C in order to obtain the density as largest …

The elastic and anelastic properties of densified B 2 O 3 glasses, melt quenched under
pressures of 2 and 4 GPa, were investigated by measuring the sound velocity and the …

We have measured the elastic moduli and the thermal expansion in permanently compacted
B 2 O 3 glasses whose structural transformations have been determined by Raman …

We present a detailed Raman scattering study of the boson peak evolution in vitreous silica
as a function of density, from the normal one up to~ 22% of densification. We show that the …

Structural changes of (Ag 2 O) x (B 2 O 3) 1-x glasses, over the range between X= 0.0 and
X= 0.14, have been monitored by Raman spectroscopy. Low temperature heat capacity …

We report on a Raman and inelastic neutron scattering investigation of the vibrational
dynamics of permanently densified v-GeO2 glasses. The comparison between the two …

Vibrational properties of crystals are well described by Debye's theory. This doesn't hold for
vitreous systems, where an excess density of low frequency vibrational states, called Boson …
