Pre-geometric Black Holes with Spherical Symmetry

Giuseppe Meluccio, Egor Pluzhnikov

Pre-geometric Gravity investigates the non-metric features of spacetime near the Planck scale, from which the gravitational interaction arises as a low-energy effective theory via…

Emergence of Gravity's Dynamical and Topological Sectors from Pre-geometry

Andrea Addazi, Giuseppe Meluccio

We identify the complete set of fundamental building blocks for a 4D pre-geometric theory of gravity. Based on a gauge theory of or coupled to a Higgs-like fiel…

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…

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 that preserves the topological pre-volume-form symmetry. Upon symmetry breaking, the theor…

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 q…

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…

Solution to the Cosmological Constant Problem from Pre-geometric Gravity

Andrea Addazi, Giuseppe Meluccio

We present a novel solution to the cosmological constant (CC) problem that requires no fine-tunings nor anthropic reasoning. In pre-geometric gravity (PGG), spacetime emerges from…

Uncertainty Principles and Non-local Black Holes

Salvatore Capozziello, Giuseppe Meluccio, Jonas R. Mureika

We discuss the Generalized Uncertainty Principle and the Extended Uncertainty Principle in the context of black hole solutions coming from non-local theories of gravity, focusing,…

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…

Pre-geometric Einstein-Cartan Field Equations and Emergent Cosmology

Giuseppe Meluccio

The field equations of pre-geometric theories of gravity are derived and analysed, both without and with matter. After the spontaneous symmetry breaking that reduces the gauge symm…

Hamiltonian Analysis of Pre-geometric Gravity

Andrea Addazi, Salvatore Capozziello, Antonino Marcianò +1

The Einstein-Cartan theory of gravity can arise from a mechanism of spontaneous symmetry breaking within the context of pre-geometric gauge theories. In this work, we develop the H…

The Weinberg no-go theorem for cosmological constant and nonlocal gravity

Salvatore Capozziello, Anupam Mazumdar, Giuseppe Meluccio

We show how a nonlocal gravitational interaction can circumvent the Weinberg no-go theorem on cosmological constant, which forbids the existence of any solution to the cosmological…

Gravity from Pre-geometry

Andrea Addazi, Salvatore Capozziello, Antonino Marciano +1

The gravitational interaction, as described by the Einstein-Cartan theory, is shown to emerge as the by-product of the spontaneous symmetry breaking of a gauge symmetry in a pre-ge…

Can nonlocal gravity really explain dark energy?

Salvatore Capozziello, Anupam Mazumdar, Giuseppe Meluccio

In view to scrutinize the idea that nonlocal modifications of General Relativity could dynamically address the dark energy problem, we investigate the evolution of the Universe at…
