Quantum Gravity phenomenology and metric formalism
Niccoló Loret, Leonardo Barcaroli, Giulia Gubitosi
In this proceedings for the MG14 conference, we discuss the construction of a phenomenology of Planck-scale effects in curved spacetimes, underline a few open issues and describe s…
Hamilton Geometry - Phase Space Geometry from Modified Dispersion Relations
Leonardo Barcaroli, Lukas K. Brunkhorst, Giulia Gubitosi +2
Quantum gravity phenomenology suggests an effective modification of the general relativistic dispersion relation of freely falling point particles caused by an underlying theory of…
Planck-scale dual-curvature lensing and spacetime noncommutativity
Giovanni Amelino-Camelia, Leonardo Barcaroli, Stefano Bianco +1
It was recently realized that Planck-scale momentum-space curvature, which is expected in some approaches to the quantum-gravity problem, can produce dual-curvature lensing, a feat…
Curved spacetimes with local -Poincaré dispersion relation
Leonardo Barcaroli, Lukas K. Brunkhorst, Giulia Gubitosi +2
We use our previously developed identification of dispersion relations with Hamilton functions on phase space to locally implement the -Poincaré dispersion relation in the momen…
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…
Kinematics of particles with quantum de Sitter symmetries
Leonardo Barcaroli, Giulia Gubitosi
We present the first detailed study of the kinematics of free relativistic particles whose symmetries are described by a quantum deformation of the de Sitter algebra, known as -…
Hamilton geometry: Phase space geometry from modified dispersion relations
Leonardo Barcaroli, Lukas K. Brunkhorst, Giulia Gubitosi +2
We describe the Hamilton geometry of the phase space of particles whose motion is characterised by general dispersion relations. In this framework spacetime and momentum space are…
Rainbow metric formalism and Relative Locality
Niccoló Loret, Leonardo Barcaroli
This proceeding is based on a talk prepared for the XIII Marcell Grossmann meeting. We summarise some results of work in progress in collaboration with Giovanni Amelino-Camelia abo…
Realization of DSR-relativistic symmetries in Finsler geometries
Giovanni Amelino-Camelia, Leonardo Barcaroli, Giulia Gubitosi +2
Finsler geometry is a well known generalization of Riemannian geometry which allows to account for a possibly non trivial structure of the space of configurations of relativistic p…
Dual redshift on Planck-scale-curved momentum spaces
Giovanni Amelino-Camelia, Leonardo Barcaroli, Giulia Gubitosi +1
Several approaches to the investigation of the quantum-gravity problem have provided "theoretical evidence" of a role for the Planck scale in characterizing the geometry of momentu…
Longitudinal and transverse relativity of spacetime locality in Planck-scale-deformed phase spaces
Niccoló Loret, Leonardo Barcaroli, Giacomo Rosati
We summarize some of the results we obtained in arXiv:1006.2126 (Physical Review Letters 106, 071301), arXiv:1102.4637 (Physics Letters B 700, 150-156) and in arXiv:1107.3334, givi…
