Asymptotic freedom for QFT in Snyder-de Sitter space
Sebastián A. Franchino-Viñas, Salvatore Mignemi
We analyze the model of a self-interacting scalar field theory in Snyder-de Sitter space. After analytically computing the one-loop beta functions {in the small nonco…
The Snyder model and quantum field theory
S. Mignemi
We review the main features of the relativistic Snyder model and its generalizations. We discuss the quantum field theory on this background using the standard formalism of noncomm…
Physical velocity of particles in relativistic curved momentum space
Salvatore Mignemi, Giacomo Rosati
We show in general that for a relativistic theory with curved momentum space, i.e.~a theory with deformed relativistic symmetries, the physical velocity of particles coincides with…
Cyclotron frequency and the quantum clock
S. Mignemi
We discuss the corrections to the orbital period of a particle in a constant magnetic field, driven by the model of noncommutative geometry recently associated to a quantum clock.…
-deformed phase spaces, Jordanian twists, Lorentz-Weyl algebra and dispersion relations
D. Meljanac, S. Meljanac, S. Mignemi +1
We consider -deformed relativistic quantum phase space and possible implementations of the Lorentz algebra. There are two ways of performing such implementations. One is a simpl…
