-Galilean and -Carrollian noncommutative spaces of worldlines
Angel Ballesteros, Giulia Gubitosi, Ivan Gutierrez-Sagredo +1
The noncommutative spacetimes associated to the -Poincaré relativistic symmetries and their "non-relativistic" (Galilei) and "ultra-relativistic" (Carroll) limits are indistingu…
Probing Lorentz-violating electrodynamics with CMB polarization
Luca Caloni, Serena Giardiello, Margherita Lembo +4
We perform a comprehensive study of the signatures of Lorentz violation in electrodynamics on the Cosmic Microwave Background (CMB) anisotropies. In the framework of the minimal St…
Deformed relativistic symmetry principles
Michele Arzano, Giulia Gubitosi, José Javier Relancio
We review the main features of models where relativistic symmetries are deformed at the Planck scale. We cover the motivations and links to other quantum gravity approaches. We des…
Could quantum gravity slow down neutrinos?
Giovanni Amelino-Camelia, Maria Grazia Di Luca, Giulia Gubitosi +2
In addition to its implications for astrophysics, the hunt for GRB neutrinos could also be significant in quantum-gravity research, since they are excellent probes of the microscop…
Fundamental decoherence from quantum spacetime
Michele Arzano, Vittorio D'Esposito, Giulia Gubitosi
We show that quantum properties of spacetime, encoded by noncommutativity at the Planck scale, lead to a generalized time evolution of quantum systems in which pure states can evol…
