Abstract:

For a model of a slowly rotating two-dimensional drum the statistics of the potential energy dissipation in avalanches is studied. Self-organized criticality occurs only for the small disks in bidisperse fillings. The large disks in bidisperse fillings as well as monodisperse fillings show a stretched exponential distribution. This is due to the absence of niches on the surface which are able to trap these disks.
