Correlation functions and fluctuation-dissipation relation in driven phase ordering systems: an exactly solvable model

The dynamics of a phase ordering system with non-conserved order parameter under a plain shear flow with rate gamma is solved-analytically in the large-N limit. A phase transition is observed at a critical temperature T-C (gamma). After a quench from a high temperature equilibrium state to a lower temperature T a nonequilibrium stationary state is entered when T > T-C(gamma), while aging dynamics characterizes the phases with T less than or equal to T-C (gamma) Two-time quantities are computed and the off-equilibrium generalization of the fluctuation-dissipation theorem is provided.
