Lorentzian Snyder spacetimes and their Galilei and Carroll limits from projective geometry
Angel Ballesteros, Giulia Gubitosi, Francisco J. Herranz
We show that the Lorentzian Snyder models, together with their Galilei and Carroll limiting cases, can be rigorously constructed through the projective geometry description of Lore…
Quantum groups, non-commutative Lorentzian spacetimes and curved momentum spaces
Ivan Gutierrez-Sagredo, Angel Ballesteros, Giulia Gubitosi +1
The essential features of a quantum group deformation of classical symmetries of General Relativity in the case with non-vanishing cosmological constant are presented. We fully…
Life of cosmological perturbations in MDR models, and the prospect of travelling primordial gravitational waves
Giulia Gubitosi, Joao Magueijo
We follow the life of a generic primordial perturbation mode (scalar or tensor) subject to modified dispersion relations (MDR), as its proper wavelength is stretched by expansion.…
Relativistic compatibility of the interacting -Poincaré model and implications for the relative locality framework
Giulia Gubitosi, Sjors Heefer
We investigate the relativistic properties under boost transformations of the -Poincaré model with multiple causally connected interactions, both at the level of its formulation…
Scales and hierachies in asymptotically safe quantum gravity: a review
Frank Saueressig, Giulia Gubitosi, Chris Ripken
The asymptotic safety program strives for a consistent description of gravity as a non-perturbatively renormalizable quantum field theory. In this framework the gravitational inter…
