Big-Bounce in Quantum f(R)-Cosmology: Polymer Dynamics with Internal Time
M. L. Limongi, S. Lo Franco, G. Montani +1
We construct the Hamiltonian formulation of the isotropic Universe in a generic metric f(R)-theory in the Jordan frame. We canonically quantize the Universe volume via a polymer fo…

Is the BKL map an intrinsic feature of the Quantum Mixmaster Universe?
S. Lo Franco, G. Montani
We study the quantum Mixmaster dynamics by constructing the corresponding Wheeler-DeWitt equation as a relativistic quantum theory in a pseudo-Riemannian Mini-superspace. The trans…

Quantum Big-Bounce as a phenomenology of RQM in the Mini-superspace
S. Lo Franco, G. Montani
We investigate the emergence of a quantum Big-Bounce in the context of an isotropic Universe, filled by a self-interacting scalar field, which plays the role of a physical clock. T…
