Spin-network states for the Bianchi I and IX cosmological models from quantum constrained symmetries
Matteo Bruno, Giovanni Montani, Edoardo Maria Panno
In this work, we implement at the quantum level the gauge-fixing conditions that relate the homogeneous SU(2) gauge theory of Ashtekar variables, describing the classical cosmologi…
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…
Cosmology in Loop Quantum Gravity: symmetry reduction preserving gauge degrees of freedom
Matteo Bruno
In this manuscript, we address the issue of the loss of SU(2) internal symmetry in Loop Quantum Cosmology and its relationship with Loop Quantum Gravity. Drawing inspiration from Y…
Is the diagonal case a general picture for Loop Quantum Cosmology?
Matteo Bruno, Giovanni Montani
The correct implementation of the Loop Quantum Gravity to the early homogeneous Universe has been the subject of a long debate in the literature because the SU(2) symmetry cannot b…
Loop Quantum Cosmology of non-diagonal Bianchi models
Matteo Bruno, Giovanni Montani
The non-diagonal Bianchi models are studied in the loop framework for their classical and quantum formulation. The expressions of the Ashtekar-Barbero-Immirzi variables and their p…
