Light Cone in a Quantum Spacetime
Flavio Mercati, Matteo Sergola
Noncommutative spacetimes are a proposed effective description of the low-energy regime of Quantum Gravity. Defining the microcausality relations of a scalar quantum field theory o…

Physical Constraints on Quantum Deformations of Spacetime Symmetries
Flavio Mercati, Matteo Sergola
In this work we study the deformations into Lie bialgebras of the three relativistic Lie algebras: de Sitter, Anti-de Sitter and Poincaré, which describe the symmetries of the thre…
