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

الأصل · EN

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.
