We study the four-dimensional Gaussian spin glass in presence of a magnetic field. Using off-equilibrium numerical simulations we have found that the probability distribution of the overlaps is built in the same way as that of the mean-field approximation with replica symmetry breaking. Finally, we have studied the violation of the fluctuation-dissipation theorem in presence of a magnetic field.

Abstract
We study the four-dimensional Gaussian spin glass in presence of a magnetic field. Using off-equilibrium numerical simulations we have found that the probability distribution of the overlaps is built in the same way as that of the mean-field approximation with replica symmetry breaking. Finally, we have studied the violation of the fluctuation-dissipation theorem in presence of a magnetic field.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
