RT Journal Article T1 Sample-to-sample fluctuations of the overlap distributions in the three-dimensional Edwards-Anderson spin glass A1 Fernández Pérez, Luis Antonio A1 Martín Mayor, Víctor A1 Muñoz Sudupe, Antonio A1 Seoane Bartolomé, Beatriz A1 Yllanes, D. AB We study the sample-to-sample fluctuations of the overlap probability densities from large-scale equilibrium simulations of the three-dimensional Edwards-Anderson spin glass below the critical temperature. Ultrametricity, stochastic stability, and overlap equivalence impose constraints on the moments of the overlap probability densities that can be tested against numerical data. We found small deviations from the Ghirlanda Guerra predictions, which get smaller as system size increases. We also focus on the shape of the overlap distribution, comparing the numerical data to a mean-field-like prediction in which finite-size effects are taken into account by substituting delta functions with broad peaks.
