Sometime ago, I found these interesting papers about self-organised criticality and quantum gravity:
Cosmology as a problem in critical phenomena – L. Smolin
Causal evolution of spin networks – F. Markopoulou, L. Smolin
Propagating spin modes in canonical quantum gravity – R. Borissov, S. Gupta
Self-organized criticality in quantum gravity – M.H. Ansari, L. Smolin
In the first two, self-organised [...]
