Brain, Rain and Forest Fires -- What is critical about criticality: In praise of the correlation function
Henrik Jeldtoft Jensen
We present a brief review of power laws and correlation functions as measures of criticality and the relation between them. By comparing phenomenology from rain, brain and the fore…
New probability distribution describing emergence in state space
Roozbeh H. Pazuki, Henrik Jeldtoft Jensen
We revisit the pairing model of state spaces with new emergent states introduced in J. Phys. A: Math. Theor. 51 375002, 2018. We facilitate our analysis by introducing a simplified…
Record dynamics of evolving metastable systems: theory and applications
Paolo Sibani, Stefan Boettcher, Henrik Jeldtoft Jensen
Record Dynamics (RD) deals with complex systems evolving through a sequence of metastable stages. These are macroscopically distinguishable and appear stationary, except for the su…
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…
Universality Classes and Information-Theoretic Measures of Complexity via Group Entropies
Piergiulio Tempesta, Henrik Jeldtoft Jensen
We introduce a class of information measures based on group entropies, allowing us to describe the information-theoretical properties of complex systems. These entropic measures ar…
