Abstract
We study dynamical roughening of strings which do not break the symmetry either parallel or vertical to the overall suspension. The suggested nonlocal dynamics enforces a buildup of long-range correlations and the system achieves self-organized criticality with a universality class which exhibits nontrivial temporal scalings and power-law-correlated activity along the string, even though only localized Gaussian noise is applied. We observe multiscaling of the temporal behavior both perpendicular and parallel (multidiffusion) to the evolving string at criticality.
