Synchronization and coarsening (without self-organized criticality) in a forest-fire model

Synchronization and coarsening (without self-organized criticality) in a forest-fire model

We study the long-time dynamics of a forest-fire model with deterministic tree growth and instantaneous burning of entire forests by stochastic lightning strikes. Asymptotically the system organizes into a coarsening self-similar mosaic of synchronized patches within which trees regrow and burn simultaneously. We show that the average patch length <L> …
