Abstract: (arXiv)
In a variety of systems which exhibit aging, the two-time response function scales as . We argue that dynamical scaling can be extended towards conformal invariance, obtaining thus the explicit form of the scaling function . This quantitative prediction is confirmed in several spin systems, both for (phase ordering) and (non-equilibrium critical dynamics). The 2D and 3D Ising models with Glauber dynamics are studied numerically, while exact results are available for the spherical model with a non-conserved order parameter, both for short-ranged and long-ranged interactions, as well as for the mean-field spherical spin glass.Note:
