Description
Systems undergoing phase-ordering kinetics after a quench into the ordered phase with $0<T<T_c$ from a fully disordered initial state and with a non-conserved order-parameter have the dynamical exponent $z=2$. The long-time behaviour of their single-time and two-time correlators, determined by the noisy initial conditions, is derived from Schrödinger-invariance. The generic properties of the correlators are derived from the Schrödinger co-variance of the four-point response functions. The autocorrelation exponent $\lambda$ is related to the passage exponent $\zeta_p$ which describes the time-scale for the cross-over into the ageing regime.
