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
for the free energy.
