Emergence of gravity from spinfoams
Elena Magliaro, Claudio Perini
We find a nontrivial regime of spinfoam quantum gravity that reproduces classical Einstein equations. This is the double scaling limit of small Immirzi parameter (gamma), large spi…
Regge gravity from spinfoams
Elena Magliaro, Claudio Perini
We consider spinfoam quantum gravity for general triangulations in the regime , namely in the combined classical limit of large areas and flipped limit of sm…
Curvature in spinfoams
Elena Magliaro, Claudio Perini
We consider spinfoam quantum gravity. We show in a simple case that the amplitude projects over a nontrivial (curved) classical geometry. This suggests that, at least for spinfoams…
Spinfoam fermions
Eugenio Bianchi, Muxin Han, Elena Magliaro +3
We describe a minimal coupling of fermions and Yang Mills fields to the loop quantum gravity dynamics. The coupling takes a very simple form.
Coherent states for FLRW space-times in loop quantum gravity
Elena Magliaro, Antonino Marciano, Claudio Perini
We construct a class of coherent spin-network states that capture proprieties of curved space-times of the Friedmann-Lamaître-Robertson-Walker type on which they are peaked. The da…
Local spin foams
Elena Magliaro, Claudio Perini
The central object of this paper is a holonomy formulation for spin foams. Within this new represen- tation, we analyze three general requirements: locality, composition law, cylin…
