The self-organized critical forest-fire model on large scales
Klaus Schenk, Barbara Drossel, Franz Schwabl
We discuss the scaling behavior of the self-organized critical forest-fire model on large length scales. As indicated in earlier publications, the forest-fire model does not show c…
Finite-size effects in the self-organized critical forest-fire model
Klaus Schenk, Barbara Drossel, Siegfried Clar +1
We study finite-size effects in the self-organized critical forest-fire model by numerically evaluating the tree density and the fire size distribution. The results show that this…
Phase Transitions in a Nonequilibrium Percolation Model
Siegfried Clar, Barbara Drossel, Klaus Schenk +1
We investigate the percolation properties of a two-state (occupied - empty) cellular automaton, where at each time step a cluster of occupied sites is removed and the same number o…
Phase Transitions in a Forest-Fire Model
Siegfried Clar, Klaus Schenk, Franz Schwabl
We investigate a forest-fire model with the density of empty sites as control parameter. The model exhibits three phases, separated by one first-order phase transition and one 'mix…
