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…

Exact enumeration of the Critical States in the Oslo Model
Alvin Chua, Kim Christensen
We determine analytically the number of recurrent states in the 1d Oslo model as a function of system size L. The solution $N_{\mathcal{R}}(L) = \frac{1+\sqrt{…

Tangled Nature: a model of evolutionary ecology
Kim Christensen, Simone A. di Collobiano, Matt Hall +1
We discuss a simple model of co-evolution. In order to emphasise the effect of interaction between individuals the entire population is subjected to the same physical environment.…
