Quadratic Palatini gravity and stable black hole remnants
Francisco S. N. Lobo, Gonzalo J. Olmo, D. Rubiera-Garcia
We present a four-dimensional Planck-scale corrected quadratic extension of General Relativity (GR) where no a priori relation between metric and connection is imposed (Palatini fo…
Planck scale physics and topology change through an exactly solvable model
Francisco S. N. Lobo, Jesus Martinez-Asencio, Gonzalo J. Olmo +1
We consider the collapse of a charged radiation fluid in a Planck-suppressed quadratic extension of General Relativity (GR) formulated à la Palatini. We obtain exact analytical sol…
Geonic black holes and remnants in Eddington-inspired Born-Infeld gravity
Gonzalo J. Olmo, D. Rubiera-Garcia, Helios Sanchis-Alepuz
We show that electrically charged solutions within the Eddington-inspired Born-Infeld theory of gravity replace the central singularity by a wormhole supported by the electric fiel…
Semiclassical geons as solitonic black hole remnants
Francisco S. N. Lobo, Gonzalo J. Olmo, D. Rubiera-Garcia
We find that the end state of black hole evaporation could be represented by non-singular and without event horizon stable solitonic remnants with masses of the order the Planck sc…
Nonsingular electrovacuum solutions with dynamically generated cosmological constant
E. I. Guendelman, Gonzalo J. Olmo, D. Rubiera-Garcia +1
We consider static spherically symmetric configurations in a Palatini extension of General Relativity including and Ricci-squared terms, which is known to replace the central…
Semiclassical geons at particle accelerators
Gonzalo J. Olmo, D. Rubiera-Garcia
We point out that in certain four-dimensional extensions of general relativity constructed within the Palatini formalism stable self-gravitating objects with a discrete mass and ch…
Importance of torsion and invariant volumes in Palatini theories of gravity
Gonzalo J. Olmo, D. Rubiera-Garcia
We study the field equations of extensions of General Relativity formulated within a metric-affine formalism setting torsion to zero (Palatini approach). We find that different (se…
Black holes in extended gravity theories in Palatini formalism
Jesus Martinez-Asencio, Gonzalo J. Olmo, D. Rubiera-Garcia
We consider several physical scenarios where black holes within classical gravity theories including and Ricci-squared corrections and formulated à la Palatini can be analyti…
Charged black holes in Palatini theories
G. J. Olmo, D. Rubiera-Garcia
In extensions of General Relativity the Palatini approach provides ghost-free theories with second-order field equations and allows to obtain charged black hole solutions wh…
