Sheared disk packings as a model system for complex dynamics

Stress fluctuations in a model of densely packed disks under steady shear reproduce many features known for complex systems. These include fat-tailed probability distributions, volatility clustering and long-range autocorrelations. Using a rescaling analysis developed in econophysics, we relate stress rises and falls to rearrangements of the disks.
