Twist deformations leading to kappa-Poincare Hopf algebra and their application to physics

Tajron Jurić, Stjepan Meljanac, Andjelo Samsarov

We consider two twist operators that lead to kappa-Poincare Hopf algebra, the first being an Abelian one and the second corresponding to a light-like kappa-deformation of Poincare…

A microscopic description of absorption in high-energy string-brane collisions

Giuseppe D'Appollonio, Paolo Di Vecchia, Rodolfo Russo +1

We study the collision of a highly energetic light closed string off a stack of Dp-branes at (sub)string-scale impact parameters and in a regime justifying a perturbative treatment…

Path integrals in Snyder space

S. Mignemi, R. Strajn

The definition of path integrals in one- and two-dimensional Snyder space is discussed in detail both in the traditional setting and in the first-order formalism of Faddeev and Jac…

Light-like $κ$ -deformations and scalar field theory via Drinfeld twist

Tajron Jurić, Stjepan Meljanac, Andjelo Samsarov

In this article we will use the Drinfeld twist leading to light-like $κ$ -deformations of Poincaré algebra. We shall apply the standard Hopf algebra methods in order to define the s…

Noncommutative scalar quasinormal modes and quantization of entropy of a BTZ black hole

Kumar S. Gupta, E. Harikumar, Tajron Jurić +2

We obtain an exact analytic expression for the quasinormal modes of a noncommutative massless scalar field in the background of a massive spinless BTZ black hole up to the first or…

Toward the classification of differential calculi on $κ$ -Minkowski space and related field theories

Tajron Juric, Stjepan Meljanac, Danijel Pikutic +1

Classification of differential forms on $κ$ -Minkowski space, particularly, the classification of all bicovariant differential calculi of classical dimension is presented. By imposi…
