Planck-scale-modified dispersion relations in homogeneous and isotropic spacetimes
Leonardo Barcaroli, Lukas K. Brunkhorst, Giulia Gubitosi +2
The covariant understanding of dispersion relations as level sets of Hamilton functions on phase space enables us to derive the most general dispersion relation compatible with hom…
Quantum-gravity-induced dual lensing and IceCube neutrinos
Giovanni Amelino-Camelia, Leonardo Barcaroli, Giacomo D'Amico +2
Momentum-space curvature, which is expected in some approaches to the quantum-gravity problem, can produce dual redshift, a feature which introduces energy dependence of the travel…
IceCube and GRB neutrinos propagating in quantum spacetime
Giovanni Amelino-Camelia, Leonardo Barcaroli, Giacomo D'Amico +2
Two recent publications have reported intriguing analyses, tentatively suggesting that some aspects of IceCube data might be manifestations of quantum-gravity-modified laws of prop…
