Stars in five dimensional Kaluza Klein gravity
D. Pugliese, G. Montani
In the five dimensional Kaluza Klein (KK) theory there is a well known class of static and electromagnetic--free KK--equations characterized by a naked singularity behavior, namely…
Semi-Classical Isotropization of the Universe during a de Sitter phase
Francesco Cianfrani, Giovanni Montani, Marco Muccino
Semi-classical states for the Wheeler-DeWitt equation of a Bianchi type I model in the presence of a scalar field are analyzed. It is outlined how this scheme can effectively descr…
The Immirzi parameter from an external scalar field
Francesco Cianfrani, Giovanni Montani
We promote the Immirzi parameter to be a minimally coupled scalar field and we analyzed the Hamiltonian constraints in the framework of Loop Quantum Gravity without the time gauge.…
Recent developments on matter dynamics within the Kaluza-Klein picture
Valentino Lacquaniti, Giovanni Montani
In this paper we propose a new approach to matter dynamics in compactified Kaluza-Klein theories. We discard the idea that the motion is geodesic and perform a simultaneous reducti…
Fluid Entropy as Time-Variable in Canonical Quantum Gravity
Francesco Cianfrani, Giovanni Montani, Simone Zonetti
The Brown-Kuchař mechanism is applied in the case of General Relativity coupled with the Schutz' model for a perfect fluid. Using the canonical formalism and manipulating the set o…
Review on Extended Approaches in the Kaluza-Klein Model
Francesco Cianfrani, Giovanni Montani
A review of the Kaluza-Klein formulation is provided, with a particular emphasis on the geometrization issue. The failure at reproducing quantum numbers of particles and the appear…
