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 …

This contribution considers recent developments in the computer modelling of amorphous
polymeric materials. Progress in our capabilities to build models for the computer simulation …

The molecular weight dependence of the fast dynamics, sound velocity, and fragility has
been studied for polystyrene (PS) and polyisobutylene (PIB). These different physical …

The nature of the low-frequency vibrations, the so-called boson peak, in spectra of glass-
forming systems remains a subject of active discussions. It appears that densification of …

We present a comparison between theoretical predictions of the generalized Langevin
equation for cooperative dynamics (CDGLE) and neutron spin echo data of dynamic …

In homogeneous (ideal) glasses, the important dimensionless stretched-exponential shape
parameter β is described by magic (not adjusted) simple fractions derived from fractal …

The changes of the dynamic properties of the nanoconfined materials vary greatly
depending on the nature of the interfaces, the chemical structure of the nanoconfined glass …

Inelastic neutron scattering was employed over recent years to investigate the influence of
spatial confinement on the dynamics of glass-forming systems. We review the common …

The theory to reconstruct the atomistic-level chain diffusion from the accelerated dynamics
that is measured in mesoscale simulations of the coarse-grained system, is applied here to …

The dynamics of cis-1, 4-polybutadiene (cis-1, 4-PB) over a wide range of temperature and
pressure conditions is explored by conducting atomistic molecular dynamics (MD) …
