Off-equilibrium fluctuation-dissipation relations in the 3d Ising Spin Glass in a magnetic field

TL;DR

This paper investigates fluctuation-dissipation relations in a 3D Ising spin glass under magnetic field, providing evidence for broken replica symmetry in the low temperature phase, with some ambiguity regarding droplet behavior.

Contribution

It offers new insights into the off-equilibrium fluctuation-dissipation relations in spin glasses with magnetic fields, supporting broken replica symmetry at low temperatures.

Findings

Results support broken replica symmetry in the low temperature phase.

Droplet behavior cannot be completely ruled out.

Findings are consistent across high and low temperature phases.

Abstract

We study the fluctuation-dissipation relations for a three dimensional Ising spin glass in a magnetic field both in the high temperature phase as well as in the low temperature one. In the region of times simulated we have found that our results support a picture of the low temperature phase with broken replica symmetry, but a droplet behavior can not be completely excluded.
