Crystal clear lessons on the microstructure of space-time and modified gravity
Francisco S. N. Lobo, Gonzalo J. Olmo, D. Rubiera-Garcia
We argue that a microscopic structure for space-time such as that expected in a quantum foam scenario, in which microscopic wormholes and other topological structures should play a…
Early-time cosmic dynamics in and extensions of Born-Infeld gravity
Andrey N. Makarenko, Sergei D. Odintsov, Gonzalo J. Olmo +1
We consider two types of modifications of Born-Infeld gravity in the Palatini formulation and explore their dynamics in the early universe. One of these families considers c…
Thick brane in gravity with Palatini dynamics
D. Bazeia, L. Losano, R. Menezes +2
This work deals with modified gravity in five dimensional spacetime. We study a thick Palatini brane, that is, a braneworld scenario described by an anti-de Sitter warped ge…
Born-Infeld gravity and its functional extensions
Sergei D. Odintsov, Gonzalo J. Olmo, D. Rubiera-Garcia
We investigate the dynamics of a family of functional extensions of the (Eddington-inspired) Born-Infeld gravity theory, constructed with the inverse of the metric and the Ricci te…
Brane-world and loop cosmology from a gravity-matter coupling perspective
Gonzalo J. Olmo, D. Rubiera-Garcia
We show that the effective brane-world and the loop quantum cosmology background expansion histories can be reproduced from a modified gravity perspective in terms of an gra…
Black holes in five-dimensional Palatini gravity and implications for the AdS/CFT correspondence
D. Bazeia, L. Losano, Gonzalo J. Olmo +1
We show that theories having second-order field equations in the context of higher-dimensional modified gravity are not restricted to the family of Lovelock Lagrangians, but can al…
Dynamical generation of wormholes with charged fluids in quadratic Palatini gravity
Francisco S. N. Lobo, Jesus Martinez-Asencio, Gonzalo J. Olmo +1
The dynamical generation of wormholes within an extension of General Relativity (GR) containing (Planck's scale-suppressed) Ricci-squared terms is considered. The theory is formula…
Microscopic wormholes and the geometry of entanglement
Francisco S. N. Lobo, Gonzalo J. Olmo, D. Rubiera-Garcia
It has recently been suggested that Einstein-Rosen (ER) bridges can be interpreted as maximally entangled states of two black holes that form a complex Einstein-Podolsky-Rosen (EPR…
