A varying gravitational constant map in asymptotically AdS black hole thermodynamics
Iarley P. Lobo, João Paulo Morais Graça, Eduardo Folco Capossoli +1
We propose a sequence of steps and a generic transformation for connecting common thermodynamic quantities considered in asymptotically anti-de Sitter black hole thermodynamics in…
Thermodynamics and remnants of Kiselev black holes in Rainbow gravity
P. H. Morais, G. V. Silva, J. P. Morais Graça +1
We do a detailed study of the thermodynamics of black holes in Rainbow gravity in the framework of the Kiselev metric, taking into account different cosmic fluids which can mimic s…
The third law of thermodynamics, non-extensivity, and energy definition in black hole physics
H. Moradpour, A. H. Ziaie, Iarley P. Lobo +3
Working in the framework of generalized statistics, the problem of establishing the third law of thermodynamics in the black hole physics is studied by focusing on Schwarzschild bl…
Joule-Thomson expansion for quantum corrected AdS-Reissner-Nordstrom black holes in Kiselev spacetime
J. P. Morais Graça, Eduardo Folco Capossoli, Henrique Boschi-Filho +1
In this work we study the inversion temperature associated with the Joule-Thomson expansion from the thermodynamics of AdS-Reissner-Nördstrom black holes. We include quantum correc…
Tsallis holographic dark energy in the Brans-Dicke cosmology
S. Ghaffari, H. Moradpour, I. P. Lobo +2
Using the Tsallis generalized entropy, holographic hypothesis and also considering the Hubble horizon as the IR cutoff, we build a holographic model for dark energy and study its c…
Scalar QNMs for higher dimensional black holes surrounded by quintessence in Rastall gravity
J. P. Morais Graça, Iarley P. Lobo
The spacetime solution for a black hole, surrounded by an exotic matter field, in Rastall gravity, is calculated in an arbitrary d-dimensional spacetime. After this, we calculate t…
Thermodynamics of Black Holes in Rastall Gravity
Iarley P. Lobo, H. Moradpour, J. P. Morais Graça +1
A promising theory in modifying general relativity by violating the ordinary energy-momentum conservation law in curved spacetime is the Rastall theory of gravity. In this theory,…
Non-Abelian cosmic string in the Starobinsky model of gravity
J. P. Morais Graça, A. de Pádua Santos, Eugênio R. Bezerra de Mello +1
In this paper, we analyze numerically the behaviour of the solutions corresponding to a non-Abelian cosmic string in the framework of the Starobinsky model, i.e. where $f(R)=R + ζR…
Cloud of strings in f(R) gravity
J. P. Morais Graça, Iarley P. Lobo, I. G. Salako
We derive the solution for a spherically symmetric string cloud configuration in a d-dimensional spacetime in the framework of f(R) theories of gravity. We also analyze some thermo…
