Noncommutative Regge-Wheeler potential: some nonperturbative results
Nikola Herceg, Tajron JuriÄ, A. Naveena Kumara +2
We study the gravitational perturbation theory of black holes in noncommutative spacetimes with noncommutativity of the type and $[Ï\stackr…
Dirac Quasinormal Modes in Noncommutative Reissner-Nordström Black Holes
Nikola Herceg, Nikola Konjik, A. Naveena Kumara +1
Noncommutative (NC) geometry provides a novel approach to probe quantum gravity effects in black hole spacetimes. This work explores Dirac quasinormal modes (QNMs) of a deformed Re…
Dirac QNM spectrum from twisted semiclassical gauge theory of gravity
Marija DimitrijeviÄ ÄiriÄ, Nikola Herceg, Nikola Konjik +2
Twisted Abelian gauge theory coupled to a noncommutative (NC) Dirac field is studied in order to infer the quasinormal mode (QNM) spectrum of the fermion matter perturbations in th…
Fermion quasinormal modes on modified RN background
Nikola Herceg, Nikola Konjik, A. Naveena Kumara +1
Noncommutative (NC) geometry may open an alternative route to quantum gravity. We study the influence of the spacetime noncommutativity on the Dirac quasinormal modes in the modifi…
Noncommutative fields in Reissner-Nordström black hole background
Milorad BežaniÄ, Marija DimitrijeviÄ ÄiriÄ, Nikola Konjik +2
In this short paper we discuss dynamics of noncommutative (NC) matter fields in the Reissner-Nordström (RN) black hole background. After reviewing the propagation of charged NC sc…
Noncommutative quasinormal modes of Schwarzschild black hole
Nikola Herceg, Tajron JuriÄ, A. Naveena Kumara +2
We study gravitational perturbations of the Schwarzschild metric in the context of noncommutative gravity. and noncommutativity are introduced through a Moyal twist of…
