Strong primordial inhomogeneities of axion-like field in Einstein-Gauss-Bonnet gravity
M. A. Krasnov, D. Z. Berkimbayev, A. Addazi +2
In this paper we consider complex scalar field with Mexican hat potential coupled with Gauss-Bonnet scalar resulting in restored U(1) symmetry at the stage of inflation, correspond…

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…

Maxim Krasnov, Daulet Berkimbayev, Andrea Addazi +2
This study offers a detailed analysis of domain wall formation and its cosmological consequences in Einstein-Gauss-Bonnet gravity coupled to a scalar field. A central aspect of the…
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…
Superoscillations in High Energy Physics and Gravity
Andrea Addazi, Qingyu Gan
We explore superoscillations within the context of classical and quantum field theories, presenting novel solutions to Klein-Gordon's, Dirac's, Maxwell's and Einstein's equations.…
Experimental test of Non-Commutative Quantum Gravity by VIP-2 Lead
Kristian Piscicchia, Andrea Addazi, Antonino Marciano +18
Pauli Exclusion Principle (PEP) violations induced by space-time non-commutativity, a class of universality for several models of Quantum Gravity, are investigated by the VIP-2 Lea…

Kristian Piscicchia, Andrea Addazi, Antonino Marciano +18
Investigations of possible violations of the Pauli Exclusion Principle represent critical tests of the microscopic space-time structure and properties. Space-time non-commutativity…

We derive a universal expression for the gravitational radiation energy spectrum at sub-leading order emitted from a generic gravitational hard scattering of multi-par…

Andrea Addazi, Massimo Bianchi, Maurizio Firrotta +1
We discuss stringy corrections to the gravitational wave signal generated in the merging of two black holes. We model the merging with two BPS compact massive objects in the…
Testing Primordial Black Holes as Dark Matter in Supergravity from Gravitational Waves
Yermek Aldabergenov, Andrea Addazi, Sergei V. Ketov
We explore the Gravitational Waves (GW) phenomenology of a simple class of supergravity models that can explain and unify inflation and Primordial Black Holes (PBH) as Dark Matter…

Yermek Aldabergenov, Andrea Addazi, Sergei V. Ketov
The modified supergravity approach is applied to describe a formation of Primordial Black Holes (PBHs) after Starobinsky inflation. Our approach naturally leads to the two-(scalar)…

The Holographic Naturalness (HN) is a new paradigm towards an explanation of the Cosmological Constant (CC) and the Higgs Hierarchy (HH) in the Universe. Motivated by the Holograph…

Andrea Addazi
We show that the formation/evaporation of Black Holes (BH) unitarizes quantum gravity at all the orders of the perturbation theory. Non-perturbative quantum effects save the scatte…

We show that our Universe lives in a topological and non-perturbative vacuum state full of a large amount of hidden quantum hairs, the hairons. We will discuss and elaborate on the…
