Comparison of the Semiclassical and Quantum Dynamics of the Bianchi I Cosmology in the Polymer and GUP Extended Paradigms
Gabriele Barca, Eleonora Giovannetti, Giovanni Montani
We compare in some detail Polymer Quantum Mechanics and the Generalized Uncertainty Principle approach to clarify to what extent we can treat them on the same footing. We show that…
Polymer Quantization of the Isotropic Universe: comparison with the Bounce of Loop Quantum Cosmology
Gabriele Barca, Eleonora Giovannetti, Federico Mandini +1
We implement Polymer Quantum Mechanics on the Hamiltonian formulation of the isotropic Universe in both the representations of the standard Ashtekar-Barbero-Immirzi connection and…
On the semiclassical and quantum picture of the Bianchi I polymer dynamics
Eleonora Giovannetti, Giovanni Montani, Silvia Schiattarella
We analyze the Bianchi I cosmology in the presence of a massless scalar field and describe its dynamics via a semiclassical and quantum polymer approach. We investigate the morphol…
An Overview on the Nature of the Bounce in LQC and PQM
Gabriele Barca, Eleonora Giovannetti, Giovanni Montani
We present a review on basic aspects of quantum cosmology in the presence of cut-off physics. We first analyze how the Wheeler-DeWitt equation in a pure metric approach describes t…
Semiclassical and quantum features of the Bianchi I cosmology in the polymer representation
E. Giovannetti, G. Montani, S. Schiattarella
We analyze the Bianchi I cosmology in the presence of a massless scalar field and describe its dynamics via a semiclassical and quantum polymer approach. We study the morphology of…
