Universality in three-dimensional Ising spin glasses: Nonequilibrium dynamics from Monte Carlo simulations

TL;DR

This paper uses Monte Carlo simulations to study the nonequilibrium dynamics of 3D Ising spin glasses, demonstrating that the universality class is independent of bond distribution form.

Contribution

It introduces a numerical method to determine critical parameters from nonequilibrium dynamics, confirming universality across different bond distributions.

Findings

Critical temperature and exponents match equilibrium results.

Universality class is independent of bond distribution.

Nonequilibrium dynamics can reliably determine critical properties.

Abstract

The non-equilibrium dynamics of the three-dimensional Edwards-Anderson spin-glass model with different bond distributions is investigated by means of Monte Carlo simulation. A numerical method is used to determine the critical temperature and the scaling exponents of the correlation and the integrated response functions. The results obtained agree with those calculated in equilibrium simulations and suggest that the universality class does not depend on the exact form of the bond distribution.
