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…
Semiclassical suppression of weak anisotropies of a generic Universe
Marco Valerio Battisti, Riccardo Belvedere, Giovanni Montani
A semiclassical mechanism which suppresses the weak anisotropies of an inhomogeneous cosmological model is developed. In particular, a wave function of this Universe having a meani…
Semi-classical isotropization of the Mixmaster Universe
Marco Valerio Battisti, Riccardo Belvedere, Giovanni Montani
A semi-classical mechanism which leads to the isotropization of the Mixmaster Universe is developed. A wave function of this Universe, which has a meaningful probabilistic interpre…
GUP vs polymer quantum cosmology: the Taub model
Marco Valerio Battisti, Orchidea Maria Lecian, Giovanni Montani
The fate of the cosmological singularity in the Taub model is discussed within the two frameworks. An internal time variable is ruled out and the only remaining degree of freedom (…
Bianchi IX in the GUP approach
Marco Valerio Battisti, Giovanni Montani
The Bianchi IX cosmological model (through Bianchi I and II) is analyzed in the framework of a generalized uncertainty principle. In particular, the anisotropies of the Universe ar…
Deformed spaces and loop cosmology
Marco Valerio Battisti
The non-singular bouncing solution of loop quantum cosmology is reproduced by a deformed minisuperspace Heisenberg algebra. This algebra is a realization of the Snyder space, is al…
