Born-Infeld Electrogravity and Dyonic Black Holes
Guadalupe Ahumada Acuña, Cecilia Bejarano, Rafael Ferraro
Born-Infeld electrogravity is defined through a Lagrangian that couples gravity and electromagnetism within a single determinantal structure. The field equations are derived in Pal…
The massive side of the electromagnetic waves
Rafael Ferraro
Stationary electromagnetic waves display aspects that are shared with massive particles, since the energy and momentum contained in a volume of sides equal to the wavelengths form…
Noether's second theorem in teleparallel gravity
Rafael Ferraro
Gauge symmetries in teleparallel gravity, together with the identities among the dynamical equations they provide, are analyzed in relation to the way they condition the coupling b…
Lorentz gauge-invariant variables in torsion-based theories of gravity
Daniel Blixt, Rafael Ferraro, Alexey Golovnev +1
General relativity dynamics can be derived from different actions -- which depart from the Einstein-Hilbert action in boundary terms -- and for different choices of the dynamical v…
Determinantal Born-Infeld Coupling of Gravity and Electromagnetism
Victor I. Afonso, Cecilia Bejarano, Rafael Ferraro +1
We study a Born-Infeld inspired model of gravity and electromagnetism in which both types of fields are treated on an equal footing via a determinantal approach in a metric-affine…
Double-extended Kerr-Schild form for electrovacuum solutions
Marcos R. A. Arcodía, Rafael Ferraro
Five-dimensional Einstein-Maxwell-Chern-Simons equations are investigated in the framework of an extended Kerr-Schild strategy to search for black holes solutions. The fulfillment…
