When a spatially uniform temperature change is imposed on a solid with more than one
phase, or on a polycrystal of a single, non-cubic phase (showing anisotropic expansion …

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 …

Since the first observation of synchrotron radiation in 1947, progress in the generation of
electromagnetic radiation using particle accelerators and in experimental methods has …

A major issue in materials science is why glasses present low-temperature thermal and
vibrational properties that sharply differ from those of crystals. In particular, long-wavelength …

This chapter reviews the topic of angular intensity correlations in X‐ray diffraction. A basic
theoretical description of quantities related to angular correlations in a simple X‐ray …

The advent of containerless processing techniques has opened the possibility of high quality
measurements of equilibrium and metastable liquids. This review focuses on the structure …

The attenuation of long-wavelength phonons (waves) by glassy disorder plays a central role
in various glass anomalies, yet it is neither fully characterized nor fully understood. Of …

Understanding the difference between the universal low-temperature properties of
amorphous and crystalline solids requires an explanation for the stronger dam** of long …

In the recent years, much attention has been devoted to the inhomogeneous nature of the
mechanical response at the nanoscale in disordered solids. Clearly, the elastic …

The disorder-induced attenuation of elastic waves is central to the universal low-temperature
properties of glasses. Recent literature offers conflicting views on both the scaling of the …
