Abstract
Simulations of large two-dimensional arrays of Josephson junctions by a classical Langevin molecular-dynamics technique on the massively parallel Connection Machine 2 are reported. Long-time relaxation studies of initially random flux configurations are performed. Hierarchical scales in both time and space are revealed when the system is under the influence of thermal noise and/or spatial disorder, as well as a perpendicular magnetic field.
