Charged fermions tunneling from stationary axially symmetric black holes with generalized uncertainty principle
Muhammad Rizwan, Muhammad Zubair Ali, Ali Övgün
In this paper, we study the tunneling of charged fermions from the stationary axially symmetric black holes using the generalized uncertainty principle (GUP) via Wentzel, Kramers,…
Reply to "Comment on Light deflection by Damour-Solodukhin wormholes and Gauss-Bonnet theorem" by Amrita Bhattacharya and Kh. Karimov Ramis
Ali Övgün
We reply to the Comment of Bhattacharya and Karimov on our paper Light deflection by Damour-Solodukhin wormholes and Gauss-Bonnet theorem [arXiv:1811.00768 [gr-qc]]. We address a n…
Hawking radiation from cubic and quartic black holes via tunneling of GUP corrected scalar and fermion particles
Wajiha Javed, Rimsha Babar, Ali Övgün
We analyze the effect of the generalized uncertainty (GUP) principle on the Hawking radiation from the hairy black hole in U(1) gauge-invariant scalar-vector-tensor theory by utili…
Weak Gravitational lensing by phantom black holes and phantom wormholes using the Gauss-Bonnet theorem
Ali Övgün, Galin Gyulchev, Kimet Jusufi
In this paper, we study the deflection of light by a class of phantom black hole and wormhole solutions in the weak limit approximation. More specifically, in the first part of thi…
Gravitational Lensing Under the Effect of Weyl and Bumblebee Gravities: Applications of Gauss-Bonnet Theorem
Ali Övgün, Kimet Jusufi, Izzet Sakalli
In this paper, we use the Gauss Bonnet theorem to obtain the deflection angle by the photons coupled to Weyl tensor in a Schwarzschild black hole and Schwarzschild-like black hole…
Holographic Thermodynamics of Accelerating Black Holes
Andres Anabalon, Michael Appels, Ruth Gregory +3
We present a careful study of accelerating black holes in anti-de Sitter spacetime, formulating the thermodynamics and resolving discrepancies that have appeared in previous invest…
Exact traversable wormhole solution in bumblebee gravity
Ali Övgün, Kimet Jusufi, İzzet Sakallı
In this study, we found a new traversable wormhole solution in the framework of a bumblebee gravity model. With these types of models, the Lorentz symmetry violation arises from th…
Complexity growth rates for AdS black holes with dyonic/ nonlinear charge/ stringy hair/ topological defects
Ali Övgün, Kimet Jusufi
In a seminal paper by Brown et al. [Phys. Rev. Lett. 116, no. 19, 191301 (2016)] a new conjecture was proposed, namely it was argued that the quantum complexity of a holographic st…
