Theory and phenomenology of relativistic corrections to the Heisenberg principle
Giovanni Amelino-Camelia, Valerio Astuti
The Heisenberg position-momentum uncertainty principle shares with the equivalence principle the role of main pillar of our current description of nature. However, in its original…
Multi-particle systems in quantum spacetime and a novel challenge for center-of-mass motion
Giovanni Amelino-Camelia, Valerio Astuti, Michelangelo Palmisano +1
In recent times there has been considerable interest in scenarios for quantum gravity in which particle kinematics is affected nonlinearly by the Planck scale, with encouraging res…
Misleading inferences from discretization of empty spacetime: Snyder-noncommutativity case study
Giovanni Amelino-Camelia, Valerio Astuti
Alternative approaches to the study of the quantum-gravity problem are handling the role of spacetime very differently. Some are focusing on the analysis of one or another novel fo…
Predictive description of Planck-scale-induced spacetime fuzziness
Giovanni Amelino-Camelia, Valerio Astuti, Giacomo Rosati
Several approaches to the quantum-gravity problem predict that spacetime should be "fuzzy", but have been so far unable to provide a crisp physical characterization of this notion.…
Gravity's weight on worldline fuzziness
Giovanni Amelino-Camelia, Valerio Astuti, Giacomo Rosati
We investigate a connection between recent results in 3D quantum gravity, providing an effective noncommutative-spacetime description, and some earlier heuristic descriptions of a…
Relative locality in a quantum spacetime and the pregeometry of -Minkowski
Giovanni Amelino-Camelia, Valerio Astuti, Giacomo Rosati
We develop a new description of the much-studied -Minkowski noncommutative spacetime, centered on representing on a single Hilbert space not only the -Minkowski coordinates,…
