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…
A correspondence between quantum error correcting codes and quantum reference frames
Sylvain Carrozza, Aidan Chatwin-Davies, Philipp A. Hoehn +1
In a gauge theory, a collection of kinematical degrees of freedom is used to redundantly describe a smaller amount of gauge-invariant information. In a quantum error correcting cod…
Relational Dynamics with Periodic Clocks
Leonardo Chataignier, Philipp A. Hoehn, Maximilian P. E. Lock +1
We discuss a systematic way in which a relational dynamics can be established relative to periodic clocks both in the classical and quantum theories, emphasising the parallels betw…
Quantum Frame Relativity of Subsystems, Correlations and Thermodynamics
Philipp A. Hoehn, Isha Kotecha, Fabio M. Mele
It was recently noted that different internal quantum reference frames (QRFs) partition a system in different ways into subsystems, much like different inertial observers in specia…
On the Role of Fiducial Structures in Minisuperspace Reduction and Quantum Fluctuations in LQC
Fabio M. Mele, Johannes Münch
In spatially non-compact minisuperpace models, spatial integrals in the Hamiltonian and symplectic form must be regularised by confining them to a finite volume , known as the…
The Physical Relevance of the Fiducial Cell in Loop Quantum Cosmology
Fabio M. Mele, Johannes Münch
A common way to avoid divergent integrals in homogeneous spatially non-compact gravitational systems is to introduce a fiducial cell by cutting-off the spatial slice at a finite re…
Quantum Corrected Polymer Black Hole Thermodynamics: Mass Relations and Logarithmic Entropy Correction
Fabio M. Mele, Johannes Münch, Stratos Pateloudis
In this paper, we continue the analysis of the effective model of quantum Schwarzschild black holes recently proposed by some of the authors in [1,2]. In the resulting spacetime th…
Mass and Horizon Dirac Observables in Effective Models of Quantum Black-to-White Hole Transition
Norbert Bodendorfer, Fabio M. Mele, Johannes Münch
In the past years, black holes and the fate of their singularity have been heavily studied within loop quantum gravity. Effective spacetime descriptions incorporating quantum geome…
(b,v)-type variables for black to white hole transitions in effective loop quantum gravity
Norbert Bodendorfer, Fabio M. Mele, Johannes Münch
Quantum gravity effects in effective models of loop quantum gravity, such as loop quantum cosmology, are encoded in the choice of so-called polymerisation schemes. Physical viabili…
Covariant Momentum Map Thermodynamics for Parametrized Field Theories
Goffredo Chirco, Marco Laudato, Fabio M. Mele
A general-covariant statistical framework capable of describing classical fluctuations of the gravitational field is a thorny open problem in theoretical physics, yet ultimately ne…
Effective Quantum Extended Spacetime of Polymer Schwarzschild Black Hole
Norbert Bodendorfer, Fabio M. Mele, Johannes Münch
The physical interpretation and eventual fate of gravitational singularities in a theory surpassing classical general relativity are puzzling questions that have generated a great…
A note on the Hamiltonian as a polymerisation parameter
Norbert Bodendorfer, Fabio M. Mele, Johannes Münch
In effective models of loop quantum gravity, the onset of quantum effects is controlled by a so-called polymerisation scale. It is sometimes necessary to make this scale phase spac…
Is limiting curvature mimetic gravity an effective polymer quantum gravity?
Norbert Bodendorfer, Fabio M. Mele, Johannes Münch
A recently proposed version of mimetic gravity incorporates a limiting curvature into general relativity by means of a specific potential depending on the d'Alembertian of the scal…
Holographic Signatures of Resolved Cosmological Singularities II: Numerical Investigations
Norbert Bodendorfer, Fabio M. Mele, Johannes Münch
A common strategy to investigate the fate of gravitational singularities in asymptotically AdS spacetimes is to translate the question from the gravitational side to a dual field t…
A Pedagogical Intrinsic Approach to Relative Entropies as Potential Functions of Quantum Metrics: the - Family
Florio M. Ciaglia, Fabio Di Cosmo, Marco Laudato +4
The so-called -z-\textit{Rényi Relative Entropies} provide a huge two-parameter family of relative entropies which includes almost all well-known examples of quantum relative en…
Tomographic Reconstruction of Quantum Metrics
Marco Laudato, Giuseppe Marmo, Fabio M. Mele +2
In the framework of quantum information geometry we investigate the relationship between monotone metric tensors uniquely defined on the space of quantum tomograms, once the tomogr…
Fisher Metric, Geometric Entanglement and Spin Networks
Goffredo Chirco, Fabio M. Mele, Daniele Oriti +1
Starting from recent results on the geometric formulation of quantum mechanics, we propose a new information geometric characterization of entanglement for spin network states in t…
