The 4D Einstein–Gauss–Bonnet theory of gravity: a review
We review the topic of 4D Einstein–Gauss–Bonnet (4DEGB) gravity, which has been the
subject of considerable interest over the past two years. Our review begins with a general …

Gravity with a generalized conformal scalar field: theory and solutions
PGS Fernandes - Physical Review D, 2021 - APS
We naturally extend general relativity with a conformally coupled scalar field by only
requiring conformal invariance of the scalar field equation of motion and not of the action …

[HTML][HTML] Cosmology from quantum potential
It was shown recently that replacing classical geodesics with quantal (Bohmian) trajectories
gives rise to a quantum corrected Raychaudhuri equation (QRE). In this article we derive the …
