Abstract

In the context of a classical example of glass-formation in 3-dimensions we exemplify how to construct a statistical mechanical theory of the glass transition. At the heart of the approach is a simple criterion for verifying a proper choice of up-scaled quasi-species that allow the construction of a theory with a finite number of 'states'. Once constructed, the theory identifies a typical scale ξ\xi that increases rapidly with lowering the temperature and which determines the α\alpha-relaxation time τα\tau_\alpha as ταexp(μξ/T)\tau_\alpha \sim \exp(\mu\xi/T) with μ\mu a typical chemical potential. The theory can predict relaxation times at temperatures that are inaccessible to numerical simulations.
