Low-frequency vibrational spectroscopy of glasses
Benoit Rufflé, Marie Foret, Bernard Hehlen
Atomic vibrations in perfect, slightly defective or mixed crystals are to a large extent well understood since many decades. Theoretical descriptions are thus in excellent agreemen…
Pressure-induced densification of vitreous silica: insight from elastic properties
Coralie Weigel, Marouane Mebarki, Sébastien Clément +3
\textit{In situ} high-pressure Brillouin light scattering experiments along loading-unloading paths are used to investigate the compressibility of vitreous silica. An accurate equa…
Vitreous silica distends in helium gas: acoustic vs. static compressibilities
Coralie Weigel, Alain Polian, Mathieu Kint +3
Sound velocities of vitreous silica are measured under He compression in the pressure range 0-6 GPa by Brillouin light scattering. It is found that the well-known anomalous maximum…
Scaling the Temperature-dependent Boson Peak of Vitreous Silica with the high-frequency Bulk Modulus derived from Brillouin Scattering Data
B. Rufflé, S. Ayrinhac, E. Courtens +4
The position and strength of the boson peak in silica glass vary considerably with temperature . Such variations cannot be explained solely with changes in the Debye energy. New…
Hypersound damping in vitreous silica measured by picosecond acoustics
A. Devos, M. Foret, S. Ayrinhac +2
The attenuation of longitudinal acoustic phonons up to frequencies nearing 250 GHz is measured in vitreous silica with a picosecond optical technique. Taking advantage of interfere…
Anharmonic vs. relaxational sound damping in glasses: II. Vitreous silica
R. Vacher, E. Courtens, M. Foret
The temperature dependence of the frequency dispersion in the sound velocity and damping of vitreous silica is reanalyzed. Thermally activated relaxation accounts for the sound att…
