The Pre-geometric Origin of Geometric Trinity of Gravity
Salvatore Capozziello, Giuseppe Meluccio
The so-called Geometric Trinity of Gravity is based on three distinct geometric features of spacetime, i.e.\ curvature, torsion and non-metricity, which give rise to equivalent dyn…
Non-local gravity effects in cosmological dynamics probed by IceCube/KM3NeT signals and dark matter relic abundance
Salvatore Capozziello, Gaetano Lambiase, Giuseppe Meluccio
Non-local gravity terms have a relevant role in determining the cosmological dynamics. Here we consider curvature- and torsion-based cosmological models where non-local terms can b…
Emergent Gravity from Topological Quantum Field Theory: Stochastic Gradient Flow Perspective away from the Quantum Gravity Problem
Andrea Addazi, Salvatore Capozziello, Jinglong Liu +3
We propose a scenario according to which the ultraviolet completion of General Relativity is realized through a stochastic gradient flow towards a topological BF theory. Specifical…
DESI and Dynamical Dark Energy from Extended Pre-geometric Gravity
Andrea Addazi, Yermek Aldabergenov, Daulet Berkimbayev +3
We consider the simplest quadratic extension of MacDowell-Mansouri pre-geometric gravity preserving the topological pre-volume form symmetry. After symmetry breaking, it becomes $(…
olographic aturalness and Information See-Saw Mechanism for Neutrinos
Andrea Addazi, Giuseppe Meluccio
The microscopic origin of the de Sitter entropy remains a central puzzle in quantum gravity related to the cosmological constant problem. Within olographic $\mathcal{N…
olographic aturalness and Pre-Geometric Gravity
Andrea Addazi, Salvatore Capozziello, Giuseppe Meluccio
The cosmological constant (CC, ) problem represents a remarkable discrepancy of about 120 orders of magnitude between the observed dark energy and its natural expectation from…
