Constant-roll inflation in the generalized SU(2) Proca theory
Juan C. Garnica, L. Gabriel Gomez, Andres A. Navarro +1
The generalized SU(2) Proca theory (GSU2P) is a variant of the well known generalized Proca theory where the vector field belongs to the Lie algebra of the SU(2) group of global tr…
Anisotropic Scalar Field Dark Energy with a Disformally Coupled Yang-Mills Field
L. Gabriel Gomez, Yeinzon Rodriguez, Juan P. Beltran Almeida
In the context of scalar-tensor theories, the inclusion of new degrees of freedom coupled non-minimally to the gravitational sector might produce some appealing effects on the cosm…
Generalized SU(2) Proca theory reconstructed and beyond
Alexander Gallego Cadavid, Yeinzon Rodriguez, L. Gabriel Gomez
As a modified gravity theory that introduces new gravitational degrees of freedom, the generalized SU(2) Proca theory (GSU2P for short) is the non-Abelian version of the well-known…
Coupled Multi-Proca Vector Dark Energy
L. Gabriel Gomez, Yeinzon Rodriguez
We study a new class of vector dark energy models where multi-Proca fields are coupled to cold dark matter by the term where is a gener…
Stability Conditions in the Generalized SU(2) Proca Theory
L. Gabriel Gomez, Yeinzon Rodriguez
Under the same spirit of the Galileon-Horndeski theories and their more modern extensions, the generalized SU(2) Proca theory was built by demanding that its action may be free of…
Towards a proof of the equivalence between FRW background expansion and statistical isotropy
Yeinzon Rodriguez, L. Gabriel Gomez, Carlos M. Nieto
We will expose in this paper our advances towards a proof of the equivalence between FRW background expansion, during some period of time that contains primordial inflation, and th…
Statistical Anisotropy in Inflationary Models with Many Vector Fields and/or Prolonged Anisotropic Expansion
L. Gabriel Gomez, Yeinzon Rodriguez
We study the most general contributions due to scalar field perturbations, vector field perturbations, and anisotropic expansion to the generation of statistical anisotropy in the…
