Directed Percolation with a Wall or Edge
Per Frojdh, Martin Howard, Kent B. Lauritsen
We examine the effects of introducing a wall or edge into a directed percolation process. Scaling ansatzes are presented for the density and survival probability of a cluster in th…
Directed percolation with an absorbing boundary
K. B. Lauritsen, K. Sneppen, M. Markosova +1
We consider directed percolation with an absorbing boundary in 1+1 and 2+1 dimensions. The distribution of cluster lifetimes and sizes depend on the boundary. The new scaling expon…
Universality classes for rice-pile models
L. A. N. Amaral, K. B. Lauritsen
We investigate sandpile models where the updating of unstable columns is done according to a stochastic rule. We examine the effect of introducing nonlocal relaxation mechanisms. W…
