The continuous development and improvement of interatomic potential models for oxide
glasses have made classical molecular dynamics a powerful computational technique …

In the previous sections the emphasis was on the coherent evolution of a spin system as a
result of the secular part of the spin Hamiltonian. The secular Hamiltonian is effectively time …

Transport of mobile ions in ionic conductors of many kinds is the key to performance in a
wide variety of applications, including portable energy sources from primary and secondary …

Silica-based glasses are of great importance in various technological fields ranging from
fiber optic wave guides, laser optics for initiating fusion reactions, to containers for …

Molecular dynamics simulations and energy-minimization techniques have been applied for
the first time to determine the whole set of elastic properties (Young's modulus, shear …

The available sites for ions in a typical disordered ionic conductor are determined. For this
purpose we devised a straightforward algorithm which via cluster analysis identifies these …

The mechanism of sodium migration in low-silica alkali-alkaline earth silicate glasses is
investigated through Car–Parrinello molecular dynamics (MD) simulations. The transport of …

We analyze multiple new issues concerning activated relaxation in glassy hard sphere fluids
and molecular and polymer liquids based on the elastically collective nonlinear Langevin …

We explore progress in understanding the behaviour of cation conducting glasses, within
the context of an evolving “dynamic structure model”(DSM). This behaviour includes: in …

Experiments have shown that the properties of the dynamics of ions in ionically conducting
glasses are similar to the dynamics of molecules in glass-forming substances. The short time …
