Indefinite probabilities in quantum spacetime: A deepening of unpredictability
Vittorio D'Esposito, Giuseppe Fabiano, Domenico Frattulillo
Non-commutative spacetime and quantum groups have been argued to capture non-classical features of spacetime and its symmetries in quantum gravity. In this letter, we show that emp…
Minimal noise in non-quantized gravity
Giuseppe Fabiano, Tomohiro Fujita, Akira Matsumura +1
An elementary prediction of the quantization of the gravitational field is that the Newtonian interaction can entangle pairs of massive objects. Conversely, in models of gravity in…
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…
Doubly Quantum Mechanics
Vittorio D'Esposito, Giuseppe Fabiano, Domenico Frattulillo +1
Motivated by the expectation that relativistic symmetries might acquire quantum features in Quantum Gravity, we take the first steps towards a theory of ''Doubly'' Quantum Mechanic…
New Physics Pathways from B Processes
Alessandra D'Alise, Giuseppe Fabiano, Domenico Frattulillo +4
We re-consider recent measures of and , now compatible with the Standard Model expectations, as well as the results for the process $\text{BR}(B_s \rightarrow μ^+…
White Paper and Roadmap for Quantum Gravity Phenomenology in the Multi-Messenger Era
R. Alves Batista, G. Amelino-Camelia, D. Boncioli +101
The unification of quantum mechanics and general relativity has long been elusive. Only recently have empirical predictions of various possible theories of quantum gravity been put…
Multiparticle states in braided lightlike -Minkowski noncommutative QFT
Giuseppe Fabiano, Flavio Mercati
In this study, we construct a 1+1-dimensional, relativistic, free, complex scalar Quantum Field Theory on the noncommutative spacetime known as lightlike -Minkowski. The associa…
The fate of Galilean relativity in minimal-length theories
Pasquale Bosso, Giuseppe Fabiano, Domenico Frattulillo +1
A number of arguments at the interplay of general relativity and quantum theory suggest an operational limit to spatial resolution, conventionally modelled as a generalized uncerta…
Positivity Conditions for Generalised Schwarzschild Space-Times
A. D'Alise, G. Fabiano, D. Frattulillo +4
We analyse the impact of positivity conditions on static spherically symmetric deformations of the Schwarzschild space-time. The metric is taken to satisfy, at least asymptotically…
Bicrossproduct vs. twist quantum symmetries in noncommutative geometries: the case of -Minkowski
Giuseppe Fabiano, Giulia Gubitosi, Fedele Lizzi +2
We discuss the quantum Poincaré symmetries of the -Minkowski spacetime, a space characterised by an angular form of noncommutativity. We show that it is possible to give t…
Total momentum and other Noether charges for particles interacting in a quantum spacetime
Giovanni Amelino-Camelia, Giuseppe Fabiano, Domenico Frattulillo
There has been strong interest in the fate of relativistic symmetries in some quantum spacetimes, also because of its possible relevance for high-precision experimental tests of re…
Quantum Euler angles and agency-dependent spacetime
Giovanni Amelino-Camelia, Vittorio D'Esposito, Giuseppe Fabiano +3
Quantum gravity is expected to introduce quantum aspects into the description of reference frames. Here we set the stage for exploring how quantum gravity induced deformations of c…
Standard model anomalies: Lepton flavour non-universality, g-2 and W-mass
Alessandra D'Alise, Guglielmo De Nardo, Maria Grazia Di Luca +8
We critically analyze the body of results that hints to the existence of New Physics from possible violations of lepton universality observed by the LHCb experiment in the ra…
