Description
A fluctuation relation for aging systems is introduced and
verified by extensive numerical simulations. It is based on
the hypothesis of partial equilibration over phase-space
regions in a scenario of entropy-driven relaxation. The
relation provides a simple alternative method, amenable of
experimental implementation, to measure replica symmetry
breaking parameters in aging systems. The connection with
the effective temperatures obtained from the
fluctuation-dissipation theorem is discussed.
