The sum of log-normal variates in geometric Brownian motion
Ole Peters, Alexander Adamou
Geometric Brownian motion (GBM) is a key model for representing self-reproducing entities. Self-reproduction may be considered the definition of life [5], and the dynamics it induc…
Tuning- and order parameter in the SOC ensemble
Ole Peters, Gunnar Pruessner
The one-dimensional Oslo model is studied under self-organized criticality (SOC) conditions and under absorbing state (AS) conditions. While the activity signals the phase transiti…
Universality under conditions of self-tuning
Ole Peters, Michelle Girvan
We study systems with a continuous phase transition that tune their parameters to maximize a quantity that diverges solely at a unique critical point. Varying the size of these sys…
Self-organized Criticality and Absorbing States: Lessons from the Ising Model
Gunnar Pruessner, Ole Peters
We investigate a suggested path to self-organized criticality. Originally, this path was devised to "generate criticality" in systems displaying an absorbing-state phase transition…
Avalanche Behavior in an Absorbing State Oslo Model
Kim Christensen, Nicholas R. Moloney, Ole Peters +1
Self-organized criticality can be translated into the language of absorbing state phase transitions. Most models for which this analogy is established have been investigated for th…
A Complexity View of Rainfall
Ole Peters, Christopher Hertlein, Kim Christensen
We show that rain events are analogous to a variety of nonequilibrium relaxation processes in Nature such as earthquakes and avalanches. Analysis of high-resolution rain data revea…
