Title: | Quantum causality constraints on kappa-Minkowski space-time | Authors: | FRANCO, Nicolas Wallet, Jean-Christophe |
Issue Date: | 2022 | Publisher: | IOP Publishing Ltd | Source: | Journal of Physics A-Mathematical and Theoretical, 55 (41) (Art N° 414007) | Abstract: | The kappa-Minkoswki space-time provides a (quantum) noncommutative deformation of the usual Minkowski space-time. However, a notion of causality is difficult to be defined in such a space with noncommutative time. In this paper, we define a notion of causality on a (1 + 1)-dimensional kappa-Minkoswki space-time using the more general framework of Lorentzian noncommutative geometry. We show that this notion allows specific causal relations, but limited by a general constraint which is a quantum generalization of the traditional speed of light limit. | Notes: | Wallet, JC (corresponding author), Univ Paris Saclay, IN2P3, CNRS, IJCLab, F-91405 Orsay, France. nicolas.franco@unamur.be; jean-christophe.wallet@universite-paris-saclay.fr |
