On the electromagnetic emission from charged test particles in a five dimensional spacetime
D. Pugliese, G. Montani, V. Lacquaniti
We study the motion of charged particles radially falling in a class of static and electromagnetic-free, five-dimensional Kaluza-Klein backgrounds. Particle dynamics in such spacet…

Implications of the gauge-fixing in Loop Quantum Cosmology
Francesco Cianfrani, Giovanni Montani
The restriction to invariant connections in a Friedmann-Robertson-Walker space-time is discussed via the analysis of the Dirac brackets associated with the corresponding gauge fixi…

Solution of the noncanonicity puzzle in General Relativity: a new Hamiltonian formulation
F. Cianfrani, M. Lulli, G. Montani
We study the transformation leading from Arnowitt, Deser, Misner (ADM) Hamiltonian formulation of General Relativity (GR) to the metric Hamiltonian formulation derived from th…
