摘要：

The aging effects of a "diffusing glass," a single elastic string diffusing in a two-dimensional disordered media assisted by thermal noise, are studied by Monte Carlo simulations. We find for the first time convincing numerical evidence of nontrivial aging effects both in the linear response against transverse force and the associated correlation function. Our results retain some important predictions of the conventional dynamical mean-field theory but also reveal remarkable differences from it.
