The non-minimal 3-form cosmology and the rise of the cuscuton
Antonio De Felice, Anamaria Hell
We consider the 3-form theory with non-minimal coupling to gravity in an expanding Universe. First, we assume that the background is homogeneous and isotropic, and that the three-f…
On the cosmological degrees of freedom of Proca field with non-minimal coupling to gravity
Antonio De Felice, Anamaria Hell
We study Proca theory with non-minimal coupling to gravity through the Ricci tensor and Ricci scalar interactions. We show that in the homogeneous and isotropic Universe together w…
Revisiting Stability in New General Relativity
Sebastian Bahamonde, Daniel Blixt, Konstantinos F. Dialektopoulos +1
We study the degrees of freedom in New General Relativity -- flat and metric compatible family of theories -- around the Minkowski background in a gauge invariant manner. First, we…
Unveiling the inconsistency of the Proca theory with non-minimal coupling to gravity
Anamaria Hell
We study the degrees of freedom of the Proca theory, non-minimally coupled to gravity. In the Minkowski background, this theory propagates five degrees of freedom -- a massive long…
