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…
Noncommutative Regge-Wheeler potential: some nonperturbative results
Nikola Herceg, Tajron Jurić, A. Naveena Kumara +2
