Observational constraints for cubic gravity theory based on third order contractions of the Riemann tensor
Mihai Marciu, Dana Maria Ioan, Mihai Dragomir
The paper studies different observational features in the case of a specific cubic gravity theory, based on third order contractions of the Riemann tensor. Considering viable cosmi…
The accelerated expansion in gravity
Mihai Marciu, Dana Maria Ioan
In the present manuscript the basic Einstein--Hilbert cosmological model is extended, by adding a new functional in the fundamental action, encoding specific g…
Physical aspects of modified gravity theories
Mihai Marciu, Dana Maria Ioan
The paper extends basic Einstein--Hilbert action by adding a newly proposed invariant constructed from a specific contraction between the Einstein tensor and the energy momentum te…
A two-field dark energy model with cubic contractions of the Riemann tensor
Mihai Marciu
The paper proposes a novel cosmological model based on a two-field scenario, where the two fields are independently coupled with a specific invariant, based on cubic contractions o…
