Thermodynamic Phase Transition of Generalized Ayon-Beato Garcia Black Holes
Elham Ghasemi, Hossein Ghaffarnejad
In this work we study thermodynamics of generalized Ayon-Beato and Garcia (ABG) black hole metric which contains three parameters named as mass , magnetic charge and dimensi…
Quantum State Dependence of Thermodynamic Phase Transition in 4D AdS Gauss-Bonnet Quantum Black Holes Surrounded With Cloud of Strings
Hossein Ghaffarnejad, Emad Yaraie, Mohammad Farsam
According to the Lovelock theorem where the model \cite{Glav} could not applicable for Einstein Gauss Bonnet (EGB) gravity in all 4D curved spacetimes, authors of the reference \ci…
Thermodynamic phase transition and Joule Thomson adiabatic expansion for dS/AdS Bardeen Black Holes with consistent 4D Gauss-Bonnet gravity
Hossein Ghaffarnejad, Elham Ghasami, Emad Yaraie +1
Instead of the work \cite{1} which in according to the Lovelock theorem it could not applicable for all types of 4D curved spacetimes of Einstein Gauss Bonnet (EGB) gravity, author…
Hairy black holes and holographic heat engine
Hossein Ghaffarnejad, Emad Yaraie, Mohammad Farsam +1
By considering AdS charged black hole in the context of extended thermodynamic as the working substance we use it as a heat engine. We investigate the effect of hairy charge on the…
The Last Lost Charge And Phase Transition In Schwarzschild AdS Minimally Coupled to a Cloud of Strings
Hossein Ghaffarnejad, Mohammad Farsam
In this paper we study the Schwarzschild AdS black hole with a cloud of string background in an extended phase space and investigate a new phase transition related to the topologic…
Holographic thermalization in AdS-Gauss-Bonnet gravity for small entangled regions
Hossein Ghaffarnejad, Emad Yaraie, Mohammad Farsam
In this paper we study the propagation of entanglement entropy after a global instantaneous quench on the CFT boundary of AdS bulk. We consider the Gauss-Bonnet model as a higher c…
Effects of quintessence dark energy on the action growth and butterfly velocity
Hossein Ghaffarnejad, Mohammad Farsam, Emad Yaraie
In this work we are about to investigate the effects of quintessence dark energy on evolution of the computational complexity relating to the AdS/CFT correspondence. We use $"compl…
Holographic entanglement entropy for small subregions and thermalization of Born-Infeld AdS black holes
H. Ghaffarnejad, M. Farsam, E. Yaraie
AApplying the Born-Infeld Anti de Sitter charged black hole metric we calculate holographic entanglement entropy (HEE) by regarding the proposal of Ryu and Takanayagi. To do so we…
Spherically symmetric curved space times from quantum fields backreaction corrections in two dimensional analogue
Hossein Ghaffarnejad
Aim of the paper is to obtain 2d analogue of the backreaction equation which will be useful to study final state of quantum perturbed spherically symmetric curved space times. Thus…
