Energy avalanches in a rice-pile model
Luis A. Nunes Amaral, Kent B. Lauritsen
We investigate a one-dimensional rice-pile model. We show that the distribution of dissipated potential energy decays as a power law with an exponent . The system thus prov…

Self-organized criticality in a rice-pile model
Luis A. Nunes Amaral, Kent B. Lauritsen
We present a new model for relaxations in piles of granular material. The relaxations are determined by a stochastic rule which models the effect of friction between the grains. We…

Impurity-induced diffusion bias in epitaxial growth
Luis A. Nunes Amaral, Joachim Krug
We introduce two models for the action of impurities in epitaxial growth. In the first, the interaction between the diffusing adatoms and the impurities is ``barrier''-like and, in…
