The spin network idea for the vacuum is John Baez's.

Spin networks, spin foams and loop quantum gravity

Loop quantum gravity is a theory that results from the canonical quantization of general relativity. A covariant (path integral) formulation of the theory is expected to be in the form of a spin foam model, such as the Barrett-Crane model. _/*Spin networks are diagrams which provide a basis for the Hilbert spaces of these theories.*/_ They also describe representation-theoretic computations that are used in computing amplitudes. This page is a collection of links to information about loop quantum gravity, spin foams, and spin networks, with some focus on parts relevant for extracting predictions from the theory.


I just translated in terms of neutrino chemistry ideas.
