Exponential corrected thermodynamics of Born-Infeld BTZ black holes in massive gravity
B. Pourhassan, M. Dehghani, S. Upadhyay +2
It is known that entropy of black hole gets correction at quantum level. Universally, these corrections are logarithmic and exponential in nature. We analyze the impacts of these q…
Black hole solutions in the quadratic Weyl conformal geometric theory of gravity
Jin-Zhao Yang, Shahab Shahidi, Tiberiu Harko
We consider numerical black hole solutions in the Weyl conformal geometry, and its associated conformally invariant Weyl quadratic gravity. In this model Einstein gravity (with a p…
On the constant roll complex scalar field inflationary models
Ali Mohammadi, Nahid Ahmadi, Mehdi Shokri
In this paper we wish to point out the possibility of using a complex scalar field in a constant roll inflationary model, as needed for observational viability. We extend the idea…
Quasinormal modes, shadow and thermodynamics of black holes coupled with nonlinear electrodynamics and cloud of strings
Dharm Veer Singh, Aradhya Shukla, Sudhaker Upadhyay
We construct an exact black hole solution for the Einstein gravity coupled with the nonlinear electrodynamics (which corresponds to the Maxwell electrodynamics in the weak field li…
Corrected thermodynamics of black hole conformally coupled to a massless scalar
Himanshu Kumar Sudhanshu, Sudhaker Upadhyay, Dharm Veer Singh +1
We study the corrected entropy due to thermal fluctuation and their effect on the thermodynamics of a conformally dressed black hole in three dimensions. We find that the thermal f…
Palatini formulation of the conformally invariant gravity theory
Tiberiu Harko, Shahab Shahidi
We investigate the field equations of the conformally invariant models of gravity with curvature-matter coupling, constructed in Weyl geometry, by using the Palatini formalism. We…
