Abstract:
Some years ago, a model was proposed to account for the observed excessive specific heat that glasses exhibit at low temperatures. Individual atoms trapped in a cavity and weakly bound to only one atom contribute to the specific heat, but not to the elastic properties, thus leading to a deviation from the normal relation between mechanical and thermodynamic properties. For quantitative calculations, the limiting model of a free particle in a cavity is used. Effects on the thermal conductivity, and relationship to other proposed theories, are discussed briefly.
