Spin Networks in Nonperturbative Quantum Gravity
@article{Baez1995SpinNI, title={Spin Networks in Nonperturbative Quantum Gravity}, author={John C. Baez}, journal={arXiv: General Relativity and Quantum Cosmology}, year={1995} }
A spin network is a generalization of a knot or link: a graph embedded in space, with edges labelled by representations of a Lie group, and vertices labelled by intertwining operators. Such objects play an important role in 3-dimensional topological quantum eld theory, functional integration on the spaceA=G of connections modulo gauge transformations, and the loop representation of quantum gravity. Here, after an introduction to the basic ideas of nonperturbative canonical quantum gravity, we…

Using the concentration of measure phenomenon, it is proved that, whenever the ratio between the boundary ∂R and the bulk edges of the graph overcomes a finite threshold, the state of the boundary is always thermal, with an entropy proportional to its area.

We study the separability of the state space of loop quantum gravity. In the standard construction, the kinematical Hilbert space of the diffeomorphism-invariant states is nonseparable. This is a…
