Lattice glass models

Abstract:
The subject of this talk is a class of lattice glass models based on the concept of geometrical frustration. Monte Carlo simulations in three dimensions show that they display a dynamical transition which is very similar to that observed in other off-lattice models and which does not depend on a specific dynamical rule. Whereas their analytic solution on a random graph with a fixed connectivity shows that they do have a discontinuous glass transition at the mean field level. As a consequence these statistical mechanics models for the glass transition bridge the gap between the phenomenology of fragile glasses and their disordered spin glass analogs, and should allow to study key issues like the existence or not of an ideal thermodynamical glass transition.
