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…
Big Bounce in Dipole Cosmology
Marco Valerio Battisti, Antonino Marciano
We derive the cosmological Big Bounce scenario from the dipole approximation of Loop Quantum Gravity. We show that a non-singular evolution takes place for any matter field and tha…
Testing quantum-spacetime relativity with gamma-ray telescopes
Giovanni Amelino-Camelia, Antonino Marciano, Marco Matassa +1
Observations of gamma-ray bursts are being used to test for a momentum dependence of the speed of photons, partly motivated by preliminary results reported in analyses of some quan…
Interplay between curvature and Planck-scale effects in astrophysics and cosmology
Antonino Marciano, Giovanni Amelino-Camelia, Nicola Rossano Bruno +3
Several recent studies have considered the implications for astrophysics and cosmology of some possible nonclassical properties of spacetime at the Planck scale. The new effects, s…
A brief overview of quantum field theory with deformed symmetries and their relation with quantum gravity
Antonino Marciano
In this letter we outline some reasons for considering a quantum field theory symmetric under quantum groups and we sketch some results obtained with collaborators in the k-Poincar…
Towards inhomogeneous loop quantum cosmology: triangulating Bianchi IX with perturbations
Antonino Marciano
This brief article sums up results obtained in arXiv:0911.2653, which develops a constrained SU(2) lattice gauge theory in the "dipole" approximation. This is a further step toward…
