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…
Aspects of non-minimally coupled curvature with power laws
Anamaria Hell, Dieter Lust
We consider a class of theories containing power-law terms in both the Ricci scalar and a scalar field, including their non-minimal couplings. As a first step, we systematically cl…
Accelerating Universe from Constraints
Anamaria Hell, Misao Sasaki
We introduce a framework of constrained scalar fields that can give rise to cosmological evolution of the Universe independent of the values of the cosmological constant. Focusing…
Conformal and pure scale-invariant gravities in d dimensions
Anamaria Hell, Dieter Lust
We consider conformal and scale-invariant gravities in d dimensions, with a special focus on pure gravity in the scale-invariant case. In four dimensions, the structure of th…
Aspects of massive gauge fields
Anamaria Hell
Massive gauge fields whose mass is introduced by hand form very intriguing theories. They depart from their massless counterparts by a straightforward modification. Yet, taking the…
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…
