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

In this review we summarize, expand, and set in context recent developments on the
thermodynamics of black holes in extended phase space, where the cosmological constant …

In this Letter, employing the generalized off-shell free energy, we treat black hole solutions
as defects in the thermodynamic parameter space. The results show that the positive and …

In this work, we present a convenient method to perform the topological analysis of black
hole thermodynamics. Utilizing the spinodal curve, thermodynamic critical points of a black …

In this paper, via employing the uniformly modified form of the generalized off-shell
Helmholtz free energy, we investigate the topological numbers for the four-dimensional …

In the recent proposal [SW Wei, Black Hole Solutions as Topological Thermodynamic
Defects, Phys. Rev. Lett. 129, 191101 (2022). PRLTAO 0031-9007 10.1103/PhysRevLett …

In this paper, we derive the consistent thermodynamics of the four-dimensional Lorentzian
Reissner-Nordström-NUT (RN-NUT), Kerr–Newman-NUT (KN-NUT), and RN-NUT-AdS …

Among the study of black hole thermodynamics, topology offers a novel approach and
perspective for classifying black hole systems. In this work, we explore the thermodynamical …

We study the topology of the thermodynamic space of four dimensional dyonic anti–de Sitter
(AdS) black hole in three different ensembles: canonical, mixed, and grand canonical …

A bstract In the generalized off-shell free energy landscape, black holes can be treated as
thermodynamic topological defects. The local topological properties of the spacetime can be …
