Mixmaster chaos in a quantum scenario:a Deformed Algebra approach
Eleonora Giovannetti
In this work, we address the question about the fate of chaos in the Mixmaster model when we promote the system at a quantum level. We consider Deformed Commutation Relations for t…
The phenomenology of Quantum Bounce in the Klein-Gordon, Wheeler-DeWitt and Dirac formalisms
Eleonora Giovannetti
We investigate the different meanings that the concept of Quantum Bounce acquires in various formalisms. The original idea refers to the phenomenology that appears in the Klein-Gor…
Fate of Mixmaster Chaos in a Deformed Algebra framework
G. Barca, E. Giovannetti
We analyze the anisotropic Bianchi models, and in particular the Bianchi Type IX known as the Mixmaster universe, where the Misner anisotropic variables obey Deformed Commutation R…
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…
Polymer representation of the Bianchi IX Cosmology in the Misner variables
Eleonora Giovannetti, Giovanni Montani
We analyze the Bianchi IX Universe in the Polymer Quantum Mechanics framework by facing both semiclassical and purely quantum effects near the cosmological singularity. We adopt Mi…
