Ricci-Tersenghi et al. Reply: In their Comment [1] to
our paper [2] de Candia and Coniglio show evidence that
the equilibrium overlap distribution P q of the frustrated
Ising lattice gas (FILG) do not coincide with the one that
could be estimated from the off-equilibrium correlation
and response functions presented in [2], for low tempera-
tures and large chemical potentials. From the theoretical
point of view one expects the relation between static and
dynamic quantities to hold as long as one-time observables
(such as energy or density) converge to the equilibrium val-
ues [3].
In order to clarify what is happening in the glassy phase
of the FILG, we have performed a new large set of simu-
lations, working mainly at bJ ` and bm 10. At
equilibrium we find a P q with two clear peaks and a
continuous part in between (as in [1]). Whether the con-
tinuous part disappears in the thermodynamical limit, thus
suggesting a one step replica symmetry broken (RSB) so-
lution, is hard to decide at present.
