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 Quasinormal Modes and the Violation of Isospectrality
Nikola Herceg, Tajron Jurić, A. Naveena Kumara +2
We explore quasinormal modes (QNMs) of the Schwarzschild black hole under a noncommutative (NC) deformation of spacetime, constructed via a Drinfeld twist formalism. In this approa…
