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…

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…

Complexity growth and shock wave geometry in AdS-Maxwell-power-Yang-Mills theory

Emad Yaraie, Hossein Ghaffarnejad, Mohammad Farsam

We study effects of non-abelian gauge fields on the holographic characteristics for instance the evolution of computational complexity. To do so we choose Maxwell-power-Yang-Mills…

Effects of a cloud of strings on the extended phase space of Einstein-Gauss-Bonnet AdS black holes

Hossein Ghaffarnejad, Emad Yaraie

In this paper we study the thermodynamics of Einstein-Gauss-Bonnet (EGB)-AdS black holes minimally coupled to a cloud of strings in an extended phase space where the cosmological c…

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…
