Planck-scale-deformed relativistic symmetries and diffeomorphisms in momentum space
Giovanni Amelino-Camelia, Stefano Bianco, Giacomo Rosati
We study the implications of a change of coordinatization of momentum space for theories with curved momentum space. We of course find that after a passive diffeomorphism the theor…
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…
Modified dispersion relations, inflation and scale invariance
Stefano Bianco, Victor Nicolai Friedhoff, Edward Wilson-Ewing
For a certain type of modified dispersion relations, the vacuum quantum state for very short wavelength cosmological perturbations is scale-invariant and it has been suggested that…
Causality and momentum conservation from relative locality
Giovanni Amelino-Camelia, Stefano Bianco, Francesco Brighenti +1
Theories with a curved momentum space, which became recently of interest in the quantum-gravity literature, can in general violate many apparently robust aspects of our current des…
From bricks to quasinormal modes: A new perspective on black hole entropy
Michele Arzano, Stefano Bianco, Olaf Dreyer
Calculations of black hole entropy based on the counting of modes of a quantum field propagating in a Schwarzschild background need to be regularized in the vicinity of the horizon…
