“…The plot of the specific heat for different values of ω f , displayed in the left panel of Fig. 3, shows the rich structure of the geometry already noticed in the literature [27][28][29][30][31]. There are positive (stable) and negative (unstable) regions alternating with each other.…”

“…This constitutes a line-element derived from the solutions studied in [21], the so-called dirty black holes. Studies on its stability [22][23][24][25][26] and some aspects of its thermodynamical behavior have been implemented in the last years [27][28][29][30][31]. However, a detailed description of the causal structure of the spacetime, the late-time behavior of the scalar QNMs, and other aspects related to corrections to the entropy and thermodynamical stability are absent in the literature.…”

In this work we consider black holes surrounded by anisotropic fluids in four dimensions. We first study the causal structure of these solutions showing some similarities and differences with Reissner–Nordström–de Sitter black holes. In addition, we consider scalar perturbations on this background geometry and compute the corresponding quasinormal modes. Moreover, we discuss the late-time behavior of the perturbations finding an interesting new feature, i.e., the presence of a subdominant power-law tail term. Likewise, we compute the Bekenstein entropy bound and the first semiclassical correction to the black hole entropy using the brick wall method, showing their universality. Finally, we also discuss the thermodynamical stability of the model.

“…It is possible to obtain such information about the phase transition of such a charged AdS black hole with a global monopole from Quevedo and HPEM metrics [78]. The phase transition of a black hole surrounded by the perfect fluid in Rastall theory has been studied using the Ruppiner and HPEM metrics, and it has been observed such a phase transition cannot be analyzed using Weinhold and Quevedo metrics [81]. It has been demonstrated that for such a black hole surrounded by the perfect fluid in the Rastall theory, it is possible to extract more information from the HPEM metrics than the Ruppiner metric [81].…”

In this paper, we will obtain quantum work for a quantum scale five dimensional Myers-Perry black hole. Unlike heat represented by Hawking radiation, the quantum work is represented by a unitary information preserving process, and becomes important for black holes only at small quantum scales. It will be observed that at such short distances, the quantum work will be corrected by non-perturbative quantum gravitational corrections. We will use the Jarzynski equality to obtain this quantum work modified by non-perturbative quantum gravitational corrections. These non-perturbative corrections will also modify the stability of a quantum Myers-Perry black hole. We will define a quantum corrected information geometry by incorporating the non-perturbative quantum corrections in the information geometry of a Myers-Perry black hole. We will use several different quantum corrected effective information metrics to analyze the stability of a quantum Myers-Perry black hole.

It is well-known that the non-extremal anti-de-Sitter (AdS) black holes show various van der Waals type criticalities, such as the P − V , T − S, Y − X, Q 2 − Ψ etc. In these cases, the phase space diagram of the relevant quantities are similar in behaviour to the isotherms on P − V diagram for the usual van der Waals gas system. The existing thermogeometric descriptions of these criticalities for the black holes deal with the whole thermogeometric manifold and its curvature. However, while observing the criticality, one only notices the behaviour of the relevant phase space variables and keep all other thermodynamic quantities as fixed. Therefore it is quite natural to investigate the geometrical behaviour of the induced metric, defined by these constant macroscopic variables, corresponding to the whole manifold of the thermogeometry. Using geometrothermodynamics (GTD), we precisely address this issue. It is observed that the extrinsic curvature of this induced metric also diverges at the critical point. This provides an alternative but important aspect of the thermogeometric description of phase transition of black holes. The entire formalism in this paper is very general as it is valid for any arbitrary black hole which shows the van der Waals type phase transition.
