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 solid electrolytes, the mobile charged defects usually perform their translational motion by
means of jump diffusion. The role of the mobile defects is played by the vacancies if most …

To date, the highest bulk lithium ion-conducting solid electrolyte is the perovskite (ABO3)-
type lithium lanthanum titanate (LLT) Li3 x La (2/3)-x□(1/3)-2 x TiO3 (0< x< 0.16) and its …

Due to the absence of microstructure and virtually infinite compositional versatility, glassy
materials are perfect candidates for rational methods to predict structure-property …

The field of dynamic processes occurring within the glassy state of matter is too broad to be
dealt with in a single article. There is, for instance, an enormous literature on the subject of …

The dielectric response of many materials exhibits universal behavior in the form of a power
law frequency dependence of the ac conductivity. This response is seen in all types of …

A model is developed for ion transport in glass which involves the creation of fluctuating
pathways within a dynamically determined structure. Key features include a site memory …

All glass-forming materials, simple liquids and polymers, show the α–β bifurcation; above a
cross-over temperature T∗, the glass α transition and the β secondary transition merge …

Arguments in favor of the electric modulus formalism are reviewed, and several
misunderstandings and misrepresentations are corrected. It is argued that different …

A study of the effect of correlated ion motion on the electrical conductivity relaxation in single-
crystalline yttria-stabilized zirconia is presented. Complex admittance in the radio frequency …
