Melvin--Bonnor and Bertotti--Robinson spacetimes with Baryonic charge
José Barrientos, Fabrizio Canfora, Adolfo Cisterna +2
In this work, we exploit a dictionary that maps solutions of the Einstein--Scalar--Maxwell theory to those of gauged Skyrme--Maxwell--Einstein models in dimensions, allowin…
From Bertotti--Robinson to Vacuum: New Exact Solutions in General Relativity via Harrison and Inversion Symmetries
José Barrientos, Adolfo Cisterna, Amaro DÃaz +1
We construct new vacuum solutions of the Einstein equations generated from electrovacuum configurations embedded in external electromagnetic backgrounds. Starting from accelerating…
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…
ModMax Electrodynamics and Holographic Magnetotransport
José Barrientos, Nicolás Cáceres, Felipe Diaz +1
We study magnetotransport in a holographic model where ModMax nonlinear electrodynamics is coupled to Einstein anti--de Sitter gravity. To incorporate momentum relaxation, we intro…
Rotating spacetimes with a free scalar field in four and five dimensions
José Barrientos, Christos Charmousis, Adolfo Cisterna +1
We construct explicit rotating solutions in Einstein's theory of relativity with a minimally coupled free scalar field rederiving and finding solutions in four or five spacetime di…
All non-expanding gravitational waves in -dimensional (anti-)de Sitter space
Marcello Ortaggio, Jakub VoldÅich, José Barrientos
We present a complete, theory-independent classification of -dimensional Kundt spacetimes of Weyl and traceless-Ricci type N. We show that these geometries consist of three inva…
