Abstract
Although glasses are not in equilibrium, for some purposes they are nearly in equilibrium. The thermodynamic properties of glasses depend on their thermal history, and when the time scale of this history is long compared to the microscopic time scale of the glass, we can compute thermodynamic quantities. In this paper, we use matched asymptotic expansions to compute the energy and entropy distribution of the simplest possible model glass, a single two-level system, in the limit of slow heating and cooling.Keywords
