Elastic models for the Non-Arrhenius Relaxation Time of Glass-Forming Liquids

Publikation: Bidrag til bog/antologi/rapportBidrag til bog/antologiForskning


We first review the phenomenology of viscous liquids and the standard models used for explaining the non-Arrhenius average relaxation time. Then the focus is turned to the so-called elastic models, arguing that these models are all equivalent in the Einstein approximation (where the short-time elastic properties are all determined by just one effective, temperature-dependent force constant). We finally discuss the connection between the elastic models and two well-established research fields of condensed-matter physics: point defects in crystals and solid-state diffusion.
