Wave optics and weak gravitational lensing of lights from spherically symmetric static scalar vector Brans Dicke black holes in presence of the cosmological constant
Hossein Ghaffarnejad
This paper has three parts. In first step we use modified scalar tensor vector Brans Dicke gravity \cite{GH0} to obtain metric solution of a spherically symmetric static black hole…
Canonical quantization of anisotropic Bianchi I cosmology from scalar vector tensor Brans Dicke gravity
Hossein Ghaffarnejad
We applied a generalized scalar-vector-tensor Brans Dicke gravity model to study canonical quantization of an anisotropic Bianchi I cosmological model. Regarding an anisotropic Har…
Thermodynamic phase transition for Quintessence Dyonic Anti de Sitter Black Holes
Hossein Ghaffarnejad, Emad Yaraie, Mohammad Farsam
We study thermodynamic of a dyonic AdS black hole surrounded by quintessence dark energy where negative cosmological constant of AdS space behaves as pressure of the black hole. We…
Dynamical system approach to scalar-vector-tensor cosmology
H. Ghaffarnejad, E. Yaraie
Using scalar-vector-tensor Brans Dicke (VBD) gravity [3] in presence of self interaction BD potential and perfect fluid matter field action we solve corresponding field equa…
Reissner-Nordström black holes statistical ensembles and first order thermodynamic phase transition
Hossein Ghaffarnejad, Mohammad Farsam
We apply Debbasch proposal to obtain mean metric of coarse graining (statistical ensemble) of quantum perturbed Reissner-Nordstöm black hole Then we seek its thermodynami…
Gravitational lensing of charged Ayon-Beato-Garcia black holes and non-linear effects of Maxwell fields
H. Ghaffarnejad, M. A. Mojahedi, H. Niad
Non-singular Ayon-Beato-Garcia (ABG) spherically symmetric static black hole (BH) with charge to mass ratio is metric solution of Born-Infeld nonlinear Maxwell-Einstein theory.…
