A scale-covariant quantum space-time
Claudio Perini, Gabriele Nunzio Tornetta
A noncommutative space-time admitting dilation symmetry was briefly mentioned in the seminal work of Doplicher, Fredenhagen and Roberts. In this paper we explicitly construct the m…
Holonomy-flux spinfoam amplitude
Claudio Perini
We introduce a holomorphic representation for the Lorentzian EPRL spinfoam on arbitrary 2-complexes. The representation is obtained via the Ashtekar-Lewandowski-Marolf-Mourão-Thiem…
Einstein-Regge equations in spinfoams
Claudio Perini
We consider spinfoam quantum gravity on a spacetime decomposition with many 4-simplices, in the double scaling limit in which the Immirzi parameter is sent to zero (flipped lim…
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…
