The scaling of the spatiotemporal response of coarsening systems was studied through simulations of 2D and 3D Ising model with Glauber dynamics. Evidence was found for Galilei invariance in the ageing regime of a phase-ordering system. The scaling functions were consistent with the prediction of local scale invariance (LSI), thereby suggesting the extension of dynamical scaling to space-time dynamical symmetry. The result provides a strong indication that LSI is indeed a true space-time dynamical symmetry of statistical systems undergoing phase-ordering kinetics. |
