Abstract
Stretched-exponential relaxation behavior observed in a one-dimensional model of pinned charge-density waves is shown to arise from anomalous deterministic diffusion confined to a closed portion of phase space. Simulation results and scaling arguments are used to relate the index of the stretched exponential to the mean-field value of the anomalous-random-walk exponent on directed percolation clusters.
