摘要：

Long-time dynamics simulations of large (128 X 128) two-dimensional arrays of Josephson junctions in a uniformly frustrating external magnetic field are reported. The results demonstrate (i) a noisy transverse voltage response to an applied current, and (ii) the dependence of the noise on both positional disorder and intrinsic dynamical symmetry breaking induced by boundaries as nucleation sites for flux-lattice defects, which propagate into the interior and control the noise characteristics.
