摘要：

We discuss the issue of temperature chaos in the Sherrington-Kirkpatrick pin glass mean-field model. We numerically compute probability distributions of the overlap among (equilibrium) configurations at two different values of the temperature, both in the spin glass phase. The situation on our medium-size systems is clearly non-chaotic, but a weak form of chaos could be emerging on very large lattices.
