Cosmology in gravity models with broken diffeomorphisms
Antonio G. Bello-Morales, Antonio L. Maroto
We study the cosmological implications of gravity models which break diffeomorphisms (Diff) invariance down to transverse diffeomorphisms (TDiff). We start from the most general gr…
TDiff in the Dark: Gravity with a scalar field invariant under transverse diffeomorphisms
Darío Jaramillo-Garrido, Antonio L. Maroto, Prado Martín-Moruno
We reflect on the possibility of having a matter action that is invariant only under transverse diffeomorphisms. This possibility is particularly interesting for the dark sector, w…
TDiff invariant field theories for cosmology
Antonio L. Maroto
We study scalar field theories invariant under transverse diffeomorphisms in cosmological contexts. We show that in the geometric optics approximation, the corresponding particles…
