Particles creation from JNW quantum perturbed black holes by minimally coupled Klein Gordon scalar free fields
Hossein Ghaffarnejad, Hamid Reza Faghani
In this work, we choose a minimal coupling interaction between massive Klein Gordon (KG) quantum scalar free fields and Janis-Newman-Winicour (JNW) spherically symmetric static bla…
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…
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…
