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…
Quantum Evolution of Hopf Algebra Hamiltonians
Michele Arzano, Antonio Del Prete, Domenico Frattulillo
In recent years, growing attention has been devoted to the possibility that theories with deformed symmetries, associated with certain models of non-commutative spacetime, may enco…
Affine Symmetry and the Group-Theoretic Basis of the Unruh Effect
Michele Arzano, Alessandra D'Alise, Simone del Rosso +1
A massless scalar field in two spacetime dimensions splits into two independent sectors of left and right-moving modes on the light cone. At the quantum level, these two sectors ca…
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…
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…
