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 …

We consider the thermodynamics of rotating and charged asymptotically de Sitter (dS) black
holes. Using Hamiltonian perturbation-theory techniques, we derive three different first-law …

In this paper, we have analyzed the information paradox and its resolution using the island
proposal in Schwarzschild de-Sitter black hole spacetime. First, we study the information …

In this work, we show that the two proposals associated with the mutual information of matter
fields can be given for an eternal Schwarzschild black hole in de Sitter spacetime. These …

When the cosmological constant, Λ, is interpreted as a thermodynamic variable in the study
of black hole thermodynamics a very rich structure emerges. It is natural to interpret Λ as a …

We investigated the properties of quantum entanglement and mutual information in the multi-
event horizon Schwarzschild-de Sitter (SdS) spacetime for massless Dirac fields. For the first …

We investigate the degradation of quantum entanglement in the Schwarzschild-de Sitter
black hole spacetime, by studying the mutual information and the logarithmic negativity for …

We define the Carrollian black holes corresponding to the limit of Schwarzschild–(anti) de
Sitter (A) dS black holes and its higher-derivative counterpart known as Schwarzschild-Bach …

It is well known that there are the black hole horizon and the cosmological horizon for the
Reissner–Nordström–de Sitter (RN-dS) spacetime. The thermodynamic quantities on the …

From solving the equations of the motion for a system of Einstein gravity coupled to a non-
linear electromagnetic field in the dS spacetime with two integral constants, we derived a …
