摘要：
Configurational entropy is of fundamental importance to understanding the universal nature of the glassy state. According to the conventional view, the configurational entropy of a liquid is 'frozen' below the glass transition temperature (T-g) all the way to absolute zero. Contrary to this, we claim that: (i) there is an entropy loss associated with the liquid to glass transition, and (ii) the configurational entropy in the glassy state vanishes at absolute zero. This paper contrasts our arguments (called the 'entropy loss' view) and the conventional view. (C) 2009 Elsevier B.V. All rights reserved.
