Planckeons as mouths of quantum wormholes and holographic origin of spacetime
Ignazio Licata, Fabrizio Tamburini, Davide Fiscaletti
We argue that Planck-scale fluctuations ``planckeons'' realize a network of non-traversable Einstein--Rosen bridges and act as holographic devices. Modeling planckeons as wormhole…
Equivalence Principle and Machian origin of extended gravity
Elmo Benedetto, Christian Corda, Ignazio Licata
Chae's analyses on GAIA observations of wide binary stars have fortified the paradigm of extended gravity with particular attention to MOND-like theories. We recall that, starting…
Testing the equivalence principle and discreteness of spacetime through the gravitational phase with quantum information technology
Fabrizio Tamburini, Ignazio Licata
We propose a new thought experiment, based on present-day Quantum Information Technologies, to measure quantum gravitational effects through the Bose-Marletto-Vedral (BMV) effect b…
Majorana quanta, string scattering, curved spacetimes and the Riemann Hypothesis
Fabrizio Tamburini, Ignazio Licata
The Riemann Hypothesis states that the Riemann zeta function admits a set of ``non-trivial'' zeros that are complex numbers supposed to have real part . Their distribut…
Kerr spacetime geometric optics for vortex beams
Fabrizio Tamburini, Fabiano Feleppa, Ignazio Licata +1
We apply the analogy between gravitational fields and optical media in the general relativistic geometric optics framework to describe how light can acquire orbital angular momentu…
Quantum oscillations in the black hole horizon
C. Corda, F. Feleppa, F. Tamburini +1
By applying Rosen's quantization approach to the historical Oppenheimer and Snyder gravitational collapse and by setting the constraints for the formation of the Schwarzschild blac…
CPT Symmetry in Projective de Sitter Universes
Ignazio Licata, Davide Fiscaletti, Leonardo Chiatti +1
In a recent work, Boyle, Finn and Turok hypothesized a model of universe that does not violate the CPT-symmetry as alternative for inflation. With this approach they described the…
General Relativistic Wormhole Connections from Planck-Scales and the ER = EPR Conjecture
Fabrizio Tamburini, Ignazio Licata
Einstein's equations of general relativity (GR) can describe the connection between events within a given hypervolume of size larger than the Planck length in terms of wo…
Hartle-Hawking boundary conditions as Nucleation by de Sitter Vacuum
F. Feleppa, I. Licata, C. Corda
It is shown that, for a de Sitter Universe, the Hartle-Hawking (HH) wave function can be obtained in a simple way starting from the Friedmann-Lemaitre-Robertson-Walker (FLRW) line…
Dark Universe and distribution of Matter as Quantum Imprinting: the Quantum Origin of Universe
I. Licata, G. Iovane, L. Chiatti +2
In this paper we analyze the Dark Matter problem and the distribution of matter through two different approaches, which are linked by the possibility that the solution of these ast…
On the general relativistic framework of the Sagnac effect
Elmo Benedetto, Fabiano Feleppa, Ignazio Licata +2
The Sagnac effect is usually considered as being a relativistic effect produced in an interferometer when the device is rotating. General relativistic explanations are known and al…
Einstein and Rastall Theories of Gravitation in Comparison
F. Darabi, H. Moradpour, I. Licata +2
We profit by a recent paper of Visser claiming that Rastall gravity is equivalent to Einstein gravity to compare the two gravitational theories in a general way. Our conclusions ar…
The commutator algebra of covariant derivative as general framework for extended gravity. The Rastall theory case and the role of the torsion
I. Licata, H. Moradpour, C. Corda
In this short review, we discuss the approach of the commutator algebra of covariant derivative to analyse the gravitational theories, starting from the standard Einstein's general…
Gravity with torsion in non-conservative Maxwell-like gauge approach
Germano Resconi, Ignazio Licata, Christian Corda
In this work we take into consideration a generalization of Gauge Theories based on the analysis of the structural characteristics of Maxwell theory, which can be considered as the…
Radiation from charged particles due to explicit symmetry breaking in a gravitational field
Fabrizio Tamburini, Mariafelicia De Laurentis, Ignazio Licata
The paradox of a free falling radiating charged particle in a gravitational field, is a well-known fascinating conceptual challenge that involves classical electrodynamics and gene…
Twisted soft photon hair implants on Black Holes
Fabrizio Tamburini, Mariafelicia De Laurentis, Ignazio Licata +1
The Hawking-Perry-Strominger (HPS) work [1] states a new controversial idea about the black hole (BH) information paradox [2-5] where BHs maximally entropize and encode information…
A Machian Request for the Equivalence Principle in Extended Gravity and non-geodesic motion
Ignazio Licata, Christian Corda, Elmo Benedetto
Starting from the origin of Einstein general relativity (GR) the request of Mach on the theory's structure has been the core of the foundational debate. That problem is strictly co…
The Archaic Universe: Big Bang, Cosmological Term and the Quantum Origin of Time in Projective Cosmology
Ignazio Licata, Leonardo Chiatti
This article proposes some cosmological reflections at the qualitative and conjectural level, suggested by the Fantappie & Arcidiacono projective relativity theory. The difference…
