The physics of the glass transition and amorphous materials continues to attract the attention
of a wide research community after decades of effort. Supercooled liquids and glasses have …

This article describes the advances that have been made over the past ten years on the
problem of fracton excitations in fractal structures. The relevant systems to this subject are so …

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

Glassy solids exhibit a wide variety of generic thermomechanical properties, ranging from
universal anomalous specific heat at cryogenic temperatures to nonlinear plastic yielding …

Numerical studies of amorphous Si show that the lowest 4% of vibrational modes are piane
wave like ('propagons') and the highest 3% of modes are localized ('locons'). The rest are …

We use extensive classical molecular-dynamics simulations to calculate the thermal
conductivity of a model silica glass. Apart from the potential parameters, this is done with no …

The correlation lengths of vitreous structures estimated from the low-frequency (boson) peak
in Raman spectra and from the width of the first sharp diffraction peak are compared. This …

We examine the vibrational spectrum of a glass of soft spheres produced by quenching an
equilibrated liquid (produced via constant-energy molecular-dynamics simulation) to zero …

From the well-recognized equivalence of the Williams-Landel-Ferry (WLF) equation and the
Vogel-Tammann-Fulcher (VTF) equation, τ= τo exp (B/[T-To]), we shall show that the …

The frequency scaling exponent of low-frequency excitations in microscopically small
glasses, which do not allow for the existence of waves (phonons), has been in the focus of …
