Abstract Stability of Schwarzschild-AdS (SAdS) black hole is investigated in Einstein–Weyl-
scalar (EWS) theory with a negative cosmological constant. Here, we introduce a quadratic …

The holographic superconductor phase transition and spontaneous scalarization are
triggered by the instability of the underlying vacuum black hole spacetime. Although both …

The homotopy analysis method (HAM) is a useful method to derive analytical approximate
solutions of black holes in modified gravity theories. In this paper, we study the Einstein …

In this paper we use the Homotopy analysis method to obtain an analytic approximation for
the entire photon trajectory in the Schwarzschild spacetime. This is usually expressed …

Abstract We consider Einstein-Weyl gravity with a minimally coupled scalar field in four
dimensional spacetime. Using the minimal geometric deformation (MGD) approach, we split …

Within the holographic framework, we investigate the Einstein‐scalar‐Gauss‐Bonnet theory
coupled with a Maxwell field in an asymptotically anti‐de Sitter (AdS) spacetime. Our …
