While I prepare the post on dimers, here is a brief one directly from a thread in physics forums. It is a talk given in Loops’07:
Entanglement Entropy in Loop Quantum Gravity – William Donnelly
The paper seems not to be in arXiv yet. The idea is that the Bekenstein-Hawking entropy is the entanglement von Neumann [...]

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 [...]
