The dynamics of volume and enthalpy recovery of glasses are studied by introducing a new fictive temperature form and the size distribution of the solid-like clusters into the original heterogeneous coupled dissipation model. The renewed model gives

The dielectric losses of poly(5-acryloxymethyl-5-ethyl-1,3-dioxacyclohexane) (PAMED) synthesized by us are investigated by fitting them using a single Cole-Cole relation or a superposition of a Havriliak-Negami relation and a Cole-Cole relation, resp

A new model describing the relaxation dynamics of nematic liquid crystals in porous hosts is presented. The model predicts a bifurcation from a single high-temperature relaxation to a bimodal low-temperature process. The bimodal relaxation shows a cr

A dynamically heterogeneous coupled dissipation scenario of the glass transition is presented. The model predicts a splitting from a high-temperature single (αβ)-relaxation to low-temperature α- and β-processes at a certain temperature, TS. The m
