Diversity as a product of interspecial interactions
Daniel Lawson, Henrik Jeldtoft Jensen, Kunihiko Kaneko
We demonstrate diversification rather than optimisation for highly interacting organisms in a well mixed biological system by means of a simple model and reference to experiment, a…
Evolution in complex systems: record dynamics in models of spin glasses, superconductors and evolutionary ecology
Henrik Jeldtoft Jensen
Recent research on the non-stationary nature of the dynamics of complex systems is reviewed through three specific models. The long time dynamics consists of a slow, decelerating b…
The species-area relationship and evolution
Daniel Lawson, Henrik Jeldtoft Jensen
Models relating to the Species-Area curve are usually defined at the species level, and concerned only with ecological timescales. We examine an individual-based model of co-evolut…
Record dynamics and the observed temperature plateau in the magnetic creep rate of type II superconductors
L. P. Oliveira, Henrik Jeldtoft Jensen, Mario Nicodemi +1
We use Monte Carlo simulations of a coarse grained three dimensional model to demonstrate that the experimentally observed approximate temperature independence of the magnetic cree…
Evolution in complex systems
Paul Anderson, Henrik Jeldtoft Jensen, L. P. Oliveira +1
What features characterise complex system dynamics? Power laws and scale invariance of fluctuations are often taken as the hallmarks of complexity, drawing on analogies with equili…
Intermittency, aging and record fluctuations
Paolo Sibani, Henrik Jeldtoft Jensen
Aging in spin glasses is analyzed via the Probability Density Function (PDF) of the heat transfer between system and bath over a small time . The PDF contains a Gaussian part,…
