Universality of free fall in Planck-scale deformed Newtonian gravity
Giuseppe Fabiano, Domenico Frattulillo, Christian Pfeifer +1
The universality of free fall is one of the most cherished principles in classical gravity. Its fate in the quantum world is one of the key questions in fundamental physics. We inv…
Planckian bound on IR/UV mixing from cold-atom interferometry
Giovanni Amelino-Camelia, Giuseppe Fabiano, Domenico Frattulillo +1
IR/UV mixing (a mechanism causing ultraviolet quantum-gravity effects to manifest themselves also in a far-infrared regime) is a rare case of feature found in several approaches to…
Covariant quantization of field theories on T-Minkowski noncommutative spacetimes
Giuseppe Fabiano, Flavio Mercati
We develop a quantization scheme for the quantum theory of a real scalar field on a class of non-commutative spacetime models collectively known as T-Minkowski. Requiring the theor…
Transverse relative locality effects in de Sitter spacetime
Giuseppe Fabiano, Domenico Frattulillo
Doubly Special Relativity (DSR) models are characterized by the deformation of relativistic symmetries at the Planck scale and constitute one of the cornerstones for quantum gravit…
On testing in-vacuo dispersion with the most energetic neutrinos: KM3-230213A case study
Giovanni Amelino-Camelia, Giacomo D'Amico, Giuseppe Fabiano +4
The phenomenology of in-vacuo dispersion, an effect such that quantum properties of spacetime slow down particles proportionally to their energies, has been a very active research…
Redshift leverage for the search of GRB neutrinos affected by quantum properties of spacetime
Giovanni Amelino-Camelia, Giacomo D'Amico, Vittorio D'Esposito +6
Some previous studies based on IceCube neutrinos had found intriguing preliminary evidence that some of them might be GRB neutrinos with travel times affected by quantum properties…
