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 …

It is widely known that the low-temperature physical properties, such as the heat capacity
and thermal conductivity, of a disordered amorphous solid are markedly different from those …

This book gives a pedagogical introduction to the physics of amorphous solids and related
disordered condensed matter systems. Important concepts from statistical mechanics such …

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 …

The physical properties of a topologically disordered amorphous material (glass), such as
heat capacity and thermal conductivity, are markedly different from those of its ordered …

Silicon in its liquid and amorphous forms occupies a unique position among amorphous
materials. Obviously important in its own right, the amorphous form is structurally close to the …

The boson peak is an excess in the phonon vibrational density of states relative to the
Debye model. It has been observed in a wide range of amorphous materials, from inorganic …

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 …

A theory for the vibrational dynamics in disordered solids [W. Schirmacher, Europhys. Lett.
73, 892 (2006) EULEEJ 0295-5075 10.1209/epl/i2005-10471-9], based on the random …

We poorly understand the properties of amorphous systems at small length scales, where a
continuous elastic description breaks down. This is apparent when one considers their …
