Universality classes for the ricepile model with absorbing properties
The absorbing "ricepile" model with stochastic toppling rules has been numerically studied. Local limited, local unlimited, nonlocal limited, and nonlocal unlimited versions of the absorbing model have been investigated. Transport properties and different dynamical regimes of all of the models have been analyzed, from the point of view of self-organized criticality. Phase transitions between different dynamical regimes were studied in detail. It was shown that the absorbing models belong to two different universality classes.
