One of the staple objectives of theoretical physics is to establish a reliable theory of quantum gravity. To achieve this goal, some fundamental scales are proposed in the modern era, e.g. two scales are proposed in the Snyder–de Sitter model. Thes

A four-dimensional solution of the classical equation of motion in the low-energy effective field theory for heterotic string theory is chosen. Popularly, this is known as Kerr–Sen black hole. Thermodynamic picture for this particular black hole is

A particular type of charged black holes is chosen, based on an action obtained from string theory. This theory predicts the existence of such black holes. Thermodynamic properties of such kinds of black holes are studied. As conjectured earlier, for

In this letter, considering the metric of a rotating polytropic black hole in the Boyer-Lindquist coordinates, at first, we derive the thermodynamic parameters such as entropy S, Helmholtz free energy F, internal energy U and Gibbs free energy G and

Here we study the thermodynamic properties of black holes like Reissner–Nordstrom black hole and Bardeen AdS black hole embedded in quintessence. We analyze the thermodynamic volume and naive geometric volume of Bardeen AdS black hole surrounded by

In this paper, we investigate the thermodynamic properties of Reissner-Nordstr\"om black holes embedded in higher $(d)$ dimensions in the framework of rainbow gravity incorporating the effects of the generalized uncertainty principle. We also examine

We consider a charged Gauss-Bonnet black hole in $d$-dimensional spacetime and examine the effect of thermal fluctuations on the thermodynamics of the concerned black hole. At first we take the first order logarithmic correction term in entropy and c

The study of thermodynamics in the view of the Hamiltonian approach is a newest tool to analyze the thermodynamic properties of the black holes. In this letter, we investigate the thermodynamics of $d$-dimensional ($d>3$) asymptotically AntideSitter

The study of the black holes in higher-dimensional space-time has got the focus mainly after developments of string theory or M -theory. Beside this, construction of brane world scenario also motivates to study the properties of higher-dimensional bl
