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…

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…
