A new exact rotating spacetime in vacuum: The Kerr--Levi-Civita Spacetime
José Barrientos, Adolfo Cisterna, Mokhtar Hassaine +2
We construct a new rotating solution of Einstein's theory in vacuum by exploiting the Lie point symmetries of the field equations in the complex potential formalism of Ernst. In pa…
Electromagnetized black holes and swirling backgrounds in nonlinear electrodynamics: The ModMax case
José Barrientos, Adolfo Cisterna, Mokhtar Hassaine +1
This work focuses on constructing electromagnetized black holes and vortex-like backgrounds within the framework of the ModMax theory--the unique nonlinear extension of Maxwell's t…
Into the MAG-verse or: Cosmology of the Complete Quadratic Metric-Affine Gravity
Damianos Iosifidis, Konstantinos Pallikaris
We study the cosmology of the complete quadratic (in torsion and nonmetricity) metric-affine gravity. Namely, we add to the scalar-curvature gravitational Lagrangian, the 17 indepe…
Mixing "Magnetic'' and "Electric'' Ehlers--Harrison transformations: The Electromagnetic Swirling Spacetime and Novel Type I Backgrounds
José Barrientos, Adolfo Cisterna, Ivan Kolář +3
In this paper, we obtain a complete list of stationary and axisymmetric spacetimes, generated from a Minkowski spacetime using the Ernst technique. We do so by operating on the ass…
Plebanśki-Demiański à la Ehlers-Harrison: Exact Rotating and Accelerating Type I Black Holes
José Barrientos, Adolfo Cisterna, Konstantinos Pallikaris
Recently, it was shown that type D black holes, encompassed in the large Plebanśki--Demiański (PD) family, exhibit a wide class of algebraically general generalizations via the app…
Exact rotating wormholes via Ehlers transformations
Adolfo Cisterna, Keanu Müller, Konstantinos Pallikaris +1
In this paper, we construct exact rotating wormholes using Ehlers solution-generating technique. This is based on the Ernst description of four-dimensional, stationary, and axially…
Biconnection Gravity as a Statistical Manifold
Damianos Iosifidis, Konstantinos Pallikaris
We formulate a bi-Connection Theory of Gravity whose Gravitational action consists of a recently defined mutual curvature scalar. Namely, we build a gravitational theory consisting…
Describing metric-affine theories anew: alternative frameworks, examples and solutions
Damianos Iosifidis, Konstantinos Pallikaris
In this work we describe metric-affine theories anew by making a change of field variables. A series of equivalent frameworks is presented and identifications are worked out in det…
Exploring the black hole spectrum of axionic Horndeski theory
Matteo Baggioli, Adolfo Cisterna, Konstantinos Pallikaris
We provide a ``user-friendly'' algorithm to systematically and rapidly obtain exact planar black hole solutions in the Einstein-Maxwell theory deformed by the most general shift- a…
Quartic Horndeski, planar black holes, holographic aspects and universal bounds
José Pablo Figueroa, Konstantinos Pallikaris
In this work, we consider a specific shift-invariant quartic Horndeski model, deriving new planar black hole solutions with axionic hair. We explore these solutions in terms of the…
Quasitopological electromagnetism and black holes
Adolfo Cisterna, Gaston Giribet, Julio Oliva +1
In this paper we extend the quasitopological electromagnetism, recently introduced by H.-S. Liu et al. [arXiv:1907.10876], to arbitrary dimensions by introducing a fundamental -…
