Phase Transition for Quenched Coupled Replicas in a Plaquette Spin Model of Glasses
Phase Transition for Quenched Coupled Replicas in a Plaquette Spin Model of Glasses
We study a three-dimensional plaquette spin model whose low temperature dynamics is glassy, due to localized defects and effective kinetic constraints. The thermodynamics of this system is smooth at all temperatures. We show that coupling it to a second system with a fixed (quenched) configuration leads to a phase transition, …
