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 …

An intriguing problem in condensed matter physics is understanding the glass transition, in
particular the dynamics in the equilibrium liquid close to vitrification. Recent advances have …

A compilation of data for small molecule organic, polymeric, and inorganic glass-forming
liquids shows that the original expectation, that there be a positive correlation between the …

Upon decreasing temperature or increasing pressure, a noncrystallizing liquid will vitrify; that
is, the structural relaxation time, τ α, becomes so long that the system cannot attain an …

The formation of a glassy disordered solid is usually observed upon cooling a melt when
crystallization can be avoided or when a system is incapable of crystallizing, as is the case …

Dielectric data on the local segmental relaxation of amorphous poly (vinyl acetate)(PVAc)
are analyzed. At atmospheric pressure, the fragility (T g-normalized temperature …

The dynamic fragilities of six polymeric materials have been compared for isobaric (constant
pressure) and isochoric (constant volume) conditions. Data were taken from the published …

A new equation describing the behavior of the structural relaxation time, τ (T, P), as a
function of both pressure and temperature, is discussed. This equation has been derived …

Dielectric relaxation measurements have been used to study the crossover in dynamics with
temperature and pressure, onset of breakdown of the Debye-Stokes-Einstein law, and the …
