Snyder-de Sitter meets the Grosse-Wulkenhaar model

S. A. Franchino-Viñas, S. Mignemi

We study an interacting $λ ϕ_{⋆}^{4}$ scalar field defined on Snyder-de Sitter space. Due to the noncommutativity as well as the curvature of this space, the renormalization of…

Asymptotic freedom for $λ ϕ_{⋆}^{4}$ QFT in Snyder-de Sitter space

Sebastián A. Franchino-Viñas, Salvatore Mignemi

We analyze the model of a self-interacting $ϕ_{⋆}^{4}$ scalar field theory in Snyder-de Sitter space. After analytically computing the one-loop beta functions {in the small nonco…

$κ$ -deformed phase spaces, Jordanian twists, Lorentz-Weyl algebra and dispersion relations

D. Meljanac, S. Meljanac, S. Mignemi +1

We consider $κ$ -deformed relativistic quantum phase space and possible implementations of the Lorentz algebra. There are two ways of performing such implementations. One is a simpl…
