The Forest Fire Model: The subtleties of criticality and scale invariance
Lorenzo Palmieri, Henrik Jeldtoft Jensen
Amongst the numerous models introduced with SOC, the Forest Fire Model (FFM) is particularly attractive for its close relationship to stochastic spreading, which is central to the…
A novel approach to the study of critical systems
Lorenzo Palmieri, Henrik Jeldtoft Jensen
We introduce a novel approach to study the critical behavior of equilibrium and non-equilibrium systems which is based on the concept of an instantaneous correlation length. We ana…
The Emergence of Weak Criticality in SOC systems
Lorenzo Palmieri, Henrik Jeldtoft Jensen
Since Self-Organised Criticality (SOC) was introduced in 1987, both the nature of the self-organisation and the criticality remains controversial. Recent observations on rain preci…
The Forest Fire Model Revisited
