Inflationary dynamics of non-minimally coupled matter-curvature theories
Miguel Barroso Varela, Orfeu Bertolami, Andreas Mantziris
This study examines how inflationary dynamics are affected by theories with a non-minimal coupling between matter and curvature. Both positive and negative corrections to th…

Density perturbations in nonminimally coupled gravity: symptoms of Lagrangian density ambiguity
Miguel Barroso Varela, Orfeu Bertolami
The evolution of density perturbations is analysed in a modified theory of gravity with a nonminimal coupling between curvature and matter. We consider the broken degeneracy betwee…

Is cosmological data suggesting a nonminimal coupling between matter and gravity?
Miguel Barroso Varela, Orfeu Bertolami
Theoretical predictions from a modified theory of gravity with a nonminimal coupling between matter and curvature are compared to data from recent cosmological surveys. We use type…
