Fragility and elastic behavior of a supercooled liquid

Abstract:
A model for the supercooled liquid is considered by taking into account its solidlike properties. We focus on how the long time dynamics is affected due to the coupling between the slowly decaying density fluctuations and the local displacement variables in the frozen liquid. Results from our model agree with the recent observation of Novikov and Sokolov [Nature (London) 431, 961 (2004)] that the fragility index m of a glass forming material is linearly related to the corresponding ratio KG of the bulk and the shear moduli.
