The Structure of the Continuum Limit of Spin Foams
Matteo Bruno, Eugenia Colafranceschi, Fabio M. Mele +1
The Spin Foam approach to quantum gravity aims at providing a covariant path-integral formulation of canonical Loop Quantum Gravity. Since spin foam amplitudes are defined through…

Unitary equivalence in Generalized Uncertainty Principle theories
Sebastiano Segreto, Matteo Bruno
We analyze the issue of unitary equivalence within Generalized Uncertainty Principle (GUP) theories in the one-dimensional case. For a deformed Heisenberg algebra, its representati…

Generalized Uncertainty Principle theory with a single constraint
Matteo Bruno, Sebastiano Segreto
We aim to analyze the consistency of the deformation of the Heisenberg algebra in the setting of constrained Hamiltonian systems, providing a procedure to induce the deformation on…
