Kovacs effect in solvable model glasses
Gerardo Aquino, Luca Leuzzi, Theo M. Nieuwenhuizen
The Kovacs protocol, based on the temperature shift experiment originally conceived by A.J. Kovacs and applied on glassy polymers, is implemented in an exactly solvable model with…
Kovacs Effect in a Fragile Glass Model
Gerardo Aquino, Luca Leuzzi, Theo M. Nieuwenhuizen
The Kovacs protocol, based on the temperature shift experiment originally conceived by A.J. Kovacs for glassy polymers, is implemented in an exactly solvable dynamical model. This…
The disordered Backgammon model
L. Leuzzi, F. Ritort
In this paper we consider an exactly solvable model which displays glassy behavior at zero temperature due to entropic barriers. The new ingredient of the model is the existence of…
Exactly Solvable Model Glass with a Facilitated Dynamics
L. Leuzzi, Th. M Nieuwenhuizen
A model glass with fast and slow processes is studied. The statics is simple and the facilitated slow dynamics is exactly solvable. The main features of a fragile glass take place:…
Inherent Structures in models for fragile and strong glass
Luca Leuzzi, Theo M. Nieuwenhuizen
An analysis of the dynamics is performed, of exactly solvable models for fragile and strong glasses, exploiting the partitioning of the free energy landscape in inherent structures…
Effective temperatures in an exactly solvable model for a fragile glass
Luca Leuzzi, Theo M. Nieuwenhuizen
A model glass is considered with one type of fast (-type) of processes, and one type of slow processes (-type). On time-scales where the fast ones are in equilibrium, the slo…
