Amorphous solids show surprisingly universal behaviour at low temperatures. The
prevailing wisdom is that this can be explained by the existence of two-state defects within …

When a system jams, it undergoes a transition from a flowing to a rigid state. Despite this
important change in the dynamics, the internal structure of the system remains disordered in …

DL_POLY is a general-purpose molecular dynamics simulation package, which was
developed by Daresbury Laboratory in the mid-1990s for the molecular simulation …

ZIF-4, a metal-organic framework (MOF) with a zeolitic structure, undergoes a crystal–
amorphous transition on heating to 300° C. The amorphous form, which we term a-ZIF, is …

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 …

Connectedness and applied stress strongly affect elasticity in solids. In various amorphous
materials, mechanical stability can be lost either by reducing connectedness or by …

Germanium dioxide (GeO 2) is a chemical analogue of SiO 2. Furthermore, it is also to some
extent a structural analogue, as the low-and high-pressure short-range order (tetrahedral …

This paper describes the progress that has been made in the past decade in the
investigation of the peculiar dynamic properties of vitreous silica (v-SiO 2) and related …

The effect of coordination on transport is investigated theoretically using random networks of
springs as model systems. An effective medium approximation is made to compute the …

A unified picture of the dynamics of supercooled liquids has emerged based on a theory of
random first-order transitions RFOTs. 1–3 The mean field approaches to structural glasses …
