Journal ArticleDOI
Glass-specific behavior in the damping of acousticlike vibrations
TL;DR: High frequency sound is observed in lithium diborate glass, Li2O-2B2O3, using Brillouin scattering of light and x rays, and it is conjecture that this relation, specific to glassy materials, might be rather common among them.
Journal ArticleDOI
Indentation deformation mechanism in glass: Densification versus shear flow
TL;DR: In this paper, the authors provide evidence for densification and volume conservative shear flow by means of atomic force microscopy topological analysis of the indentation profile and volume on as-quenched and densified specimens (pressure up to 25 GPa).
Journal ArticleDOI
Elastic Softness of Hybrid Lead Halide Perovskites.

TL;DR: The findings suggest that low thermal conductivity and hot phonon bottleneck phenomena are expected to be enhanced by low elastic stiffness, particularly in the case of the ultrasoft α-FAPbI_{3}.
Journal ArticleDOI
Boson peak and its relation to acoustic attenuation in glasses.
TL;DR: Good agreement without adjustable parameters is obtained with models including the existence of nonacoustic vibrational modes at THz frequency, providing in many cases a comprehensive picture for a range of glass anomalies.
Journal ArticleDOI
Revealing the fast atomic motion of network glasses

TL;DR: Following the evolution of the structural relaxation in a sodium silicate glass, it is found that this fast dynamics is accompanied by the absence of any detectable aging, suggesting a decoupling of the relaxation time and the viscosity in the glass.
