In this work, both extended phase space and holographic equipartition approaches are employed to develop an exact Van der Waals description of non-rotating $$D=4$$D=4 SAdS black holes as an ensemble of spacetime atoms. After a possible microscopical interaction model is introduced, statistical mechanics techniques, with certain heuristic gravitational constraints, are used to derive the equation of state and the Bekenstein–Hawking entropy. The procedure is generalized to the charged $$D=4$$D=4… 

The Kerr–Newman black hole as a rotating Van der Waals gas

In this work we employ the horizon approach for the thermodynamics of black holes, together with holographic equipartition, to show that the Kerr–Newman black hole can be considered as a rotating Van

Interaction potential and thermo-correction to the equation of state for AdS black holes

The microscopic structure of black holes remains a challenging subject. In this paper, based on the well-accepted fact that a black hole can be mapped to a thermodynamic system, we start from the

Interaction potential and thermo-correction to the equation of state for thermally stable Schwarzschild anti-de Sitter black holes

The microscopic structure of black holes remains a challenging subject. In this paper, based on the well-accepted fact that black holes can be mapped to thermodynamic systems, we make a preliminary

Quasilocal Smarr relations for static black holes

Generalized Smarr relations in terms of quasilocal variables are obtained for Schwarzschild and Reissner-Nordstrom black holes. The approach is based on gravitational path integrals with finite

Recently, a proposal has been made to figure out the expected discrete nature of spacetime at the smallest scales in terms of atoms of spacetime, capturing their effects through a scalar , related to

Thermodynamics of spherically symmetric black holes in scale-dependent gravity

In this work we extend the first law of thermodynamics to spherically symmetric black hole solutions in the context of scale-dependent gravity. After deriving generalized expressions for both the

Black holes as gases of punctures with a chemical potential: Bose-Einstein condensation and logarithmic corrections to the entropy

We study the thermodynamical properties of black holes when described as gases of indistinguishable punctures with a chemical potential. In this picture, which arises from loop quantum gravity, the

The Chemistry of Black Holes

I provide a short overview of black hole thermodynamics in extended phase space, where the cosmological constant is interpreted as thermodynamic pressure. This leads to an understanding of black

Extended phase space thermodynamics for charged and rotating black holes and Born-Infeld vacuum polarization

A bstractWe investigate the critical behaviour of charged and rotating AdS black holes in d spacetime dimensions, including effects from non-linear electrodynamics via the Born-Infeld action, in an

Statistics, holography, and black hole entropy in loop quantum gravity

In loop quantum gravity the quantum states of a black hole horizon are produced by point-like discrete quantum geometry excitations (or {\em punctures}) labelled by spin $j$. The excitations possibly

We review recent developments on the thermodynamics of black holes in extended phase space, where the cosmological constant is interpreted as thermodynamic pressure and treated as a thermodynamic

Insight into the microscopic structure of an AdS black hole from a thermodynamical phase transition.

The number density suffers a sudden change accompanied by a latent heat when the black hole system crosses the small-large black hole coexistence curve, while when the system passes the critical point, it encounters a second-order phase transition with a vanishing latent heat due to the continuous change of the number density.

In a theory where the cosmological constant $\Lambda$ or the gauge coupling constant $g$ arises as the vacuum expectation value, its variation should be included in the first law of thermodynamics

Black Hole Chemistry

The mass of a black hole has traditionally been identified with its energy. We describe a new perspective on black hole thermodynamics, one that identifies the mass of a black hole with chemical
