Complex materials are composed of basic units which invariably interact with anharmonic
potentials. It is well known that the dynamics of systems with anharmonic interaction are …

In this review a systematic analysis of the potential energy landscape (PEL) of glass-forming
systems is presented. Starting from the thermodynamics, the route towards the dynamics is …

In comparing a material's resistance to distort under mechanical load rather than to alter in
volume, Poisson's ratio offers the fundamental metric by which to compare the performance …

Very different materials are named “Glass,” with Young's modulus (E) and Poisson's ratio (ν)
extending from 5 to 180 GPa and from 0.1 to 0.4, respectively, in the case of bulk inorganic …

We present a topological model for the composition dependence of glass transition
temperature and fragility. Whereas previous topological models are derived for zero …

If liquids, polymers, bio-materials, metals and molten salts can avoid crystallization during
cooling or compression, they freeze into a microscopically disordered solid-like state, a …

Recent progress in the description of glassy relaxation and aging are reviewed for the wide
class of network-forming materials such as GeO 2, Ge x Se 1− x, silicates (SiO 2–Na 2 O) or …

We investigate the effect of antiplasticizer additives on long-wavelength thermodynamic
properties relating to the efficiency of molecular packing (density ρ and isothermal …

The emergence of the solid state in glass-forming materials upon cooling is accompanied by
changes in both thermodynamic and viscoelastic properties and by a precipitous drop in …

Understanding the microscopic mechanism of the transition of glass remains one of the most
challenging topics in Condensed Matter Physics. What controls the sharp slowing down of …
