Abstract:Année de publication : 2005
We show that point-like defect model of glasses cannot explain thermodynamic properties of glass-formers, as for example the excess specific heat close to the glass transition, contrary to the claim of J.P. Garrahan, D. Chandler [Proc. Natl. Acad. Sci. {\bf 100}, 9710 (2003)]. More general models and approaches in terms of extended defects are also discussed.
