Short-scale Emergence of Classical Geometry, in Euclidean Loop Quantum Gravity
arXiv:1603.07931
Abstract
We study the euclidean covariant loop-quantum-gravity vertex numerically, using a cylindrically symmetric boundary state and a convenient value of the Barbero-Immirzi parameter. We show that a classical geometry emerges already at low spin. We also recognise the appearance of the degenerate configurations.
