dyonic black holes in gravity's rainbow

S. Panahiyan, S. H. Hendi, N. Riazi

In this paper, we investigate thermodynamical structure of dyonic black holes in the presence of gravity's rainbow. We confirm that for super magnetized and highly pressurized scen…

Criticality and extended phase space thermodynamics of AdS black holes in higher curvature massive gravity

Seyed Hossein Hendi, Ali Dehghani

Considering de Rham-Gabadadze-Tolley theory of massive gravity coupled with (ghost free) higher curvature terms arisen from the Lovelock Lagrangian, we obtain charged AdS black hol…

Complexity of the Einstein-Born-Infeld-Massive Black holes

S. H. Hendi, B. Bahrami Asl

Motivated by interesting correspondence between computational complexity in a CFT and the action evaluated on a WDW patch in the bulk, we study the complexity of the Einstein-massi…

Thermal fluctuations of charged black holes in gravity's rainbow

Sudhaker Upadhyay, Seyed Hossein Hendi, Shahram Panahiyan +1

Quantum fluctuation effects have an irrefutable role in high energy physics. Such fluctuation can be often regarded as a correction of infrared (IR) limit. In this paper, the effec…

Revisiting Agegraphic Dark Energy in Brans-Dicke Cosmology

M. Abdollahi Zadeh, A. Sheykhi

We explore a spatially homogeneous and isotropic Friedmann-Robertson-Walker (FRW) universe which is filled with agegraphic dark energy (ADE) with mutual interaction with pressurele…

Black Hole Remnant in Massive Gravity

B. Eslam Panah, S. H. Hendi, Y. C. Ong

The possibility of a nonzero graviton mass has been widely pursued in the literature. In this work we investigate a black hole solution in massive gravity with a degenerate fiducia…

Ghost dark energy in the DGP braneworld

M. Abdollahi Zadeh, A. Sheykhi

We investigate the ghost model of dark energy in the framework of DGP braneworld. We explore the cosmological consequences of this model by determining the equation of state parame…

A Note on Tsallis Holographic Dark Energy

M. Abdollahi Zadeh, A. Sheykhi, H. Moradpour +1

We explore the effects of considering various infrared (IR) cutoffs, including the particle horizon, Ricci horizon and Granda-Oliveros (GO) cutoffs, on the properties of Tsallis ho…

Modified Friedmann Equations from Tsallis Entropy

Ahmad Sheykhi

It was shown by Tsallis and Cirto that thermodynamical entropy of a gravitational system such as black hole must be generalized to the non-additive entropy, which is given by $S_h=…

White dwarfs in de Rham-Gabadadze-Tolley like massive gravity

B. Eslam Panah, H. L. Liu

The existence of possible massive white dwarfs more than the Chandrasekhar limit (, in which is mass of the sun) is a challenging topic. In this regard…

Stability of HDE model with sign-changeable interaction in Brans-Dicke theory

M. Abdollahi Zadeh, A. Sheykhi

We consider the Brans-Dicke (BD) theory of gravity and explore the cosmological implications of the sign-changeable interacting holographic dark energy (HDE) model in the backgroun…

Tsallis Holographic Dark Energy

M. Tavayef, A. Sheykhi, Kazuharu Bamba +1

Employing the modified entropy-area relation suggested by Tsallis and Cirto \cite{non3}, and the holographic hypothesis, a new holographic dark energy (HDE) model is proposed. Cons…

Asymptotically (A)dS dilaton black holes with nonlinear electrodynamics

S. Hajkhalili, A. Sheykhi

It is well-known that with an appropriate combination of three Liouville-type dilaton potentials, one can construct charged dilaton black holes in an (anti)-de Sitter [(A)dS] space…

Thermodynamic description and quasinormal modes of adS black holes in Born-Infeld massive gravity with a non-abelian hair

Seyed Hossein Hendi, Mehrab Momennia

We construct a new class of asymptotically (a)dS black hole solutions of Einstein-Yang-Mills massive gravity in the presence of Born-Infeld nonlinear electrodynamics. The obtained…
