Description
κ-Poincarè model is a phenomenological model of quantized spacetime, that is based on the κ-Poincarè Hopf algebra. It aims to deform Special Relativity, by incorporating the second invariant energy scale – Planck scale. It is primarily a model of curved momentum space and so the construction of the universal spacetime is not trivial.
In this talk I will quickly introduce the model based on the κ-Poincarè Hopf algebra focusing mainly on its algebraic part. Then, I will discuss the semi-classical regime of this model, that consists of point-like, relativistic, free particles living in a flat spacetime. Finally, I will explain phenomenon known as non-locality that is observed when applying translations and discuss how it changes, when taking into consideration boosted observers.
