Testing gravitational waveforms in full General Relativity
Fabio D'Ambrosio, Francesco Gozzini, Lavinia Heisenberg +3
We perform a comprehensive analysis of state-of-the-art waveform models, focusing on their predictions concerning kick velocity and inferred gravitational wave memory. In our inves…
Primordial fluctuations from quantum gravity: 16-cell topological model
Pietropaolo Frisoni, Francesco Gozzini, Francesca Vidotto
We present a numerical analysis of an Hartle-Hawking state for the early universe, in the deep quantum regime, computed using the covariant Loop Quantum Gravity formalism, in a tru…
Markov Chain Monte Carlo methods for graph refinement in Spinfoam Cosmology
Pietropaolo Frisoni, Francesco Gozzini, Francesca Vidotto
We study the behaviour of the Lorentzian Engle-Pereira-Rovelli-Livine spinfoam amplitude with homogeneous boundary data, under a graph refinement going from five to twenty boundary…
Numerical analysis of the self-energy in covariant Loop Quantum Gravity
Pietropaolo Frisoni, Francesco Gozzini, Francesca Vidotto
We study numerically the first order radiative corrections to the self-energy, in covariant loop quantum gravity. We employ the recently developed 'sl2cfoam-next' spinfoam amplitud…
A high-performance code for EPRL spin foam amplitudes
Francesco Gozzini
We present , a high-performance software library for computing Lorentzian EPRL spin foam amplitudes. The library improves on previous codes by many o…
A Wick rotation for EPRL spin foam models
Pietro Dona, Francesco Gozzini, Alessandro Nicotra
We show that the Euclidean and Lorentzian EPRL vertex amplitudes of covariant Loop Quantum Gravity are related through a ``Wick rotation'' of the real Immirzi parameter to purely i…
