摘要
Using the renormalization group method we investigate the nonequilibrium relaxation of the (Cardy-Ostlund) 2D random sine-Gordon model, which describes pinned arrays of lines. Its statics exhibit a marginal (theta=0) glass phase for T<T-g described by a line of fixed points. We obtain the universal scaling functions for two-time dynamical response and correlations near T-g for various initial conditions, as well as the autocorrelation exponent. The fluctuation dissipation ratio is found to be nontrivial and continuously dependent on T.
