Self-organized branching processes: Avalanche models with dissipation
Kent Bækgaard Lauritsen, Stefano Zapperi, H. Eugene Stanley
We explore in the mean-field approximation the robustness with respect to dissipation of self-organized criticality in sandpile models. To this end, we generalize a recently introd…
Self-Organized Branching Processes: A Mean-Field Theory for Avalanches
Stefano Zapperi, Kent Baekgaard Lauritsen, H. Eugene Stanley
We discuss mean-field theories for self-organized criticality and the connection with the general theory of branching processes. We point out that the nature of the self-organizati…
Statistical Laws and Mechanics of Voronoi Random Lattices
K. B. Lauritsen, C. Moukarzel, H. J. Herrmann
We investigate random lattices where the connectivities are determined by the Voronoi construction, while the location of the points are the dynamic degrees of freedom. The Voronoi…
