Revisiting the energy-momentum squared gravity
Mihai Marciu
In this paper we have revisited the energy-momentum squared gravity theory, by taking into account the second derivative of the matter Lagrangian with respect to the metric, encaps…

Dynamical interplay between coupled scalar dark sectors and gravity
Mihai Marciu
We explore a novel cosmological model based on coupled fields in the framework of scalar tensor theories, considering the specific interplay between gravity and scalar fields. The…

Matter--Geometry interplay in new scalar tensor theories of gravity
Mihai Marciu
The paper studies the possible interplay between matter and geometry in scalar tensor theories of gravitation where the energy--momentum tensor is directly coupled with the Einstei…
