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 Dimitrijević Ćirić, 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 Bežanić, Marija Dimitrijević Ćirić, 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 sca…
Noncommutative Reissner-Nordström black hole from noncommutative charged scalar field
Marija Dimitrijević Ćirić, Tajron Jurić, Nikola Konjik +2
Within the framework of noncommutative (NC) deformation of gauge field theory by the angular twist, we first rederive the NC scalar and gauge field model from our previous papers a…
Noncommutative scalar field theory in a curved background: duality between noncommutative and effective commutative description
Marija Dimitrijević Ćirić, Nikola Konjik, Andjelo Samsarov
We study a noncommutative (NC) deformation of a charged scalar field, minimally coupled to a classical (commutative) Reissner Nordstrom like background. The deformation is performe…
Braided Quantum Electrodynamics
Marija Dimitrijević Ćirić, Nikola Konjik, Voja Radovanović +1
The homotopy algebraic formalism of braided noncommutative field theory is used to define the explicit example of braided electrodynamics, that is, gauge theory min…
Propagation of spinors on a noncommutative spacetime: equivalence of the formal and the effective approach
Marija Dimitrijević Ćirić, Nikola Konjik, Andjelo Samsarov
Some noncommutative (NC) theories posses a certain type of dualities that are implicitly built within their structure. In this paper we establish still another example of this kind…
-algebra of braided electrodynamics
Marija Dimitrijević Ćirić, Nikola Konjik, Voja Radovanović +2
Using the recently developed formalism of braided noncommutative field theory, we construct an explicit example of braided electrodynamics, that is, a noncommutative gauge t…
Search for footprints of quantum spacetime in black hole QNM spectrum
Marija Dimitrijević Ćirić, Nikola Konjik, Andjelo Samsarov
Black hole (BH) perturbation is followed by a ringdown phase which is dominated by quasinormal modes (QNM). These modes may provide key signature of the gravitational waves. The pr…
Noncommutative scalar field in the non-extremal Reissner-Nordström background: QNM spectrum
Marija Dimitrijević Ćirić, Nikola Konjik, Andjelo Samsarov
In our previous work [18] we constructed a model of a noncommutative, charged and massive scalar field based on the angular twist. Then we used this model to analyze the motion of…
Noncommutative field theory from angular twist
Marija Dimitrijevic Ciric, Nikola Konjik, Maxim A. Kurkov +2
We consider a noncommutative field theory with space-time -commutators based on an angular noncommutativity, namely a solvable Lie algebra: the Euclidean in two dimension. T…
Noncommutative Electrodynamics from Model of Noncommutative Gravity
Marija Dimitrijević Ćirić, Dragoljub Gočanin, Nikola Konjik +1
In our previous work we have constructed a model of noncommutative (NC) gravity based on gauge symmetry. In this paper we extend the model by adding matter fields:…
Noncommutative Scalar Quasinormal Modes of the Reissner Nordström Black Hole
Marija Dimitrijević Ćirić, Nikola Konjik, Andjelo Samsarov
Aiming to search for a signal of space-time noncommutativity, we study a quasinormal mode spectrum of the Reissner Nordström black hole in the presence of a deformed space-time str…
