Building a case for a Planck-scale-deformed boost action: the Planck-scale particle-localization limit
Giovanni Amelino-Camelia
"Doubly-special relativity" (DSR), the idea of a Planck-scale Minkowski limit that is still a relativistic theory, but with both the Planck scale and the speed-of-light scale as no…
Exotic Acceleration Processes and Fundamental Physics
Giovanni Amelino-Camelia
Gamma-ray bursts and ultra-high-energy cosmic rays provide an important testing ground for fundamental physics. A simple-minded analysis of some gamma-ray bursts would lead to a hu…
Black-hole thermodynamics with modified dispersion relations and generalized uncertainty principles
Giovanni Amelino-Camelia, Michele Arzano, Yi Ling +1
In several approaches to the quantum-gravity problem evidence has emerged of the validity of a "GUP" (a Generalized position-momentum Uncertainty Principle) and/or a "MDR" (a modif…
A glimpse at the flat-spacetime limit of quantum gravity using the Bekenstein argument in reverse
Giovanni Amelino-Camelia, Michele Arzano, Andrea Procaccini
An insightful argument for a linear relation between the entropy and the area of a black hole was given by Bekenstein using only the energy-momentum dispersion relation, the uncert…
The Search for Quantum Gravity Signals
G. Amelino-Camelia, C. Lämmerzahl, A. Macias +1
We give an overview of ongoing searches for effects motivated by the study of the quantum-gravity problem. We describe in greater detail approaches which have not been covered in r…
