Running Einstein Constant and a Possible Vacuum State of the Universe
Giovanni Montani, Giulia Maniccia, Elisa Fazzari +1
We propose a revised formulation of General Relativity for cosmological settings, in which the Einstein constant varies with the energy density of the Universe. We demonstrate that…
Dynamics of the Mixmaster Universe in a non-commutative Generalized Uncertainty Principle framework
Sebastiano Segreto, Giovanni Montani
In this work, we examine the dynamical aspects of the cosmological Mixmaster model within the framework of non-commutative generalized uncertainty principle (GUP) theories. The the…
Generalized Uncertainty Principle theories and their classical interpretation
Matteo Bruno, Sebastiano Segreto, Giovanni Montani
In this work, we show that it is possible to define a classical system associated with a Generalized Uncertainty Principle (GUP) theory via the implementation of a consistent sympl…
Analyzing the influence of graviton fluctuations on the inflationary spectrum with a Kuchař-Torre clock
Giulia Maniccia, Giovanni Montani, Marco Tosoni
This paper focuses on the search for a coherent and consistent formulation to describe quantum gravity corrections to Quantum Field Theory. We implement two fundamental ingredients…
Quantum Gravity Corrections to the inflationary spectrum in a Bohmian approach
Giulia Maniccia, Giovanni Montani
A precise interpretation of the Universe wave function is forbidden in the spirit of the Copenhagen School since a precise notion of measure operation cannot be satisfactorily defi…
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…
n-dimensional non-commutative GUP quantization and application to the Bianchi I model
Sebastiano Segreto, Giovanni Montani
We analyse a n-dimensional Generalized Uncertainty Principle (GUP) quantization framework, characterized by a non-commutative nature of the configurational variables. First, we ide…
