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…
The Role of Time Gauge in Quantizing Gravity
Francesco Cianfrani, Giovanni Montani
We present the Hamiltonian formulation of General Relativity with the Holst formulation in a generic local Lorentz frame. In particular, we outline that a Gauss constraint is infer…
Towards Loop Quantum Gravity without the time gauge
Francesco Cianfrani, Giovanni Montani
The Hamiltonian formulation of the Holst action is reviewed and it is provided a solution of second-class constraints corresponding to a generic local Lorentz frame. Within this sc…
Dirac equations in curved space-time versus Papapetrou spinning particles
Francesco Cianfrani, Giovanni Montani
We find out classical particles, starting from Dirac quantum fields on a curved space-time, by an eikonal approximation and a localization hypothesis for amplitudes. We recover the…
Definition of a time variable with Entropy of a perfect fluid in Canonical Quantum Gravity
Francesco Cianfrani, Giovanni Montani, Simone Zonetti
The Brown-Kuchar 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 of…
On the geometrization of the electro-magnetic interaction for a spinning particle
Francesco Cianfrani, Irene Milillo, Giovanni Montani
We outline that, in a Kaluza-Klein framework, not only the electro-magnetic field can be geometrized, but also the dynamics of a charged spinning particle can be inferred from the…
