Rejuvenation in the random energy model
Abstract
We show that the Random Energy Model has interesting rejuvenation properties in its frozen phase. Different "susceptibilities" to temperature changes, for the free energy and for other ("magnetic" ) observables, can be computed exactly. These susceptibilities diverge at the transition temperature, as (1 - T/Tc)-3 for the free energy.
