Quantum gravity predictions for black hole interior geometry

E Alesci, S Bahrami, D Pranzetti - Physics Letters B, 2019 - Elsevier
In a previous work we derived an effective Hamiltonian constraint for the Schwarzschild
geometry starting from the full loop quantum gravity Hamiltonian constraint and computing …

Asymptotically de Sitter universe inside a Schwarzschild black hole

E Alesci, S Bahrami, D Pranzetti - Physical Review D, 2020 - APS
Extending our previous analysis, we study the interior of a Schwarzschild black hole derived
from a partial gauge fixing of the full loop quantum gravity Hilbert space, this time including …

Improved gauge-unfixing formalism through a prototypical second-class system

JA Neto, WD Morais, R Thibes - Europhysics Letters, 2023 - iopscience.iop.org
We contextualize the improved gauge-unfixing (GU) formalism within a rather general
prototypical second-class system, obtaining a corresponding first-class equivalent …

Operators of quantum-reduced loop gravity from the perspective of full loop quantum gravity

I Mäkinen - Physical Review D, 2020 - APS
Quantum-reduced loop gravity is a model of loop quantum gravity, which—from the technical
point of view—is characterized by the remarkably simple form of its basic operators. In this …

Bianchi I effective dynamics in quantum reduced loop gravity

E Alesci, G Botta, G Luzi, GV Stagno - Physical Review D, 2019 - APS
The effective quantum dynamics of Bianchi I spacetime is addressed within the statistical
regularization scheme in quantum reduced loop gravity. The case of a minimally coupled …

Effective Space-time Geometry for Black Holes and Cosmology

R Dekhil - thesis.unipd.it
Effective space-time geometries can be derived by evolving initial data sets through a
modified Hamiltonian obtained within a canonical approach to quantum gravity. This …
