Three-dimensional static and spinning black hole solutions of the Einstein-Klein-Gordon system are obtained for a particular scalar field configuration. At large distances, and for a …
We consider higher-order derivative gauge field corrections that arise in the fundamental context of dimensional reduction of string theory and Lovelock-inspired gravities and obtain …
In the framework of a simple gravitational theory that contains a scalar field minimally coupled to gravity, we investigate the emergence of analytic black-hole solutions with …
In this work, we delve into the model of the shift symmetric and parity-preserving beyond Horndeski theory in all its generality. We present an explicit algorithm to extract static and …

We study the Einstein-Euler-Heisenberg theory in the presence of a self interacting scalar field, minimally coupled to gravity. We solve analytically the field equations for the …

We consider Einstein-Maxwell-dilaton theory in (2+ 1) dimensions where the coupling between the scalar field and the Maxwell invariant is the dilatonic coupling f (ϕ)= exp (-2 α …
The construction of quasitopological gravities in three-dimensions requires coupling a scalar field to the metric. As shown in [arXiv: 2104.10172], the resulting “electromagnetic” …

We study the corrected entropy due to thermal fluctuation and their effect on the thermodynamics of a conformally dressed black hole in three dimensions. We find that the …
We model gravitating relativistic 3D spheres composed of an anisotropic fluid in which the radial and transverse components of the pressure correspond to the vacuum energy and a …
