Structure formation in an anisotropic universe: Eulerian perturbation theory
Juan P. Beltrán Almeida, Josué Motoa-Manzano, Jorge Noreña +2
We present an effective Eulerian description, in the non-relativistic regime, of the growth of cosmological perturbations around a homogeneous but anisotropic Bianchi I spacetime b…
Anisotropic solid dark energy
J. Motoa-Manzano, J. Bayron Orjuela-Quintana, Thiago S. Pereira +1
In this paper, we study a triad of inhomogeneous scalar fields, known as "solid", as a source of homogeneous but anisotropic dark energy. By using a dynamical system approach, we f…
de Sitter symmetries and inflationary scalar-vector models
Juan P. Beltrán Almeida, Josué Motoa-Manzano, César A. Valenzuela-Toledo
In this paper, we study the correspondence between a field theory in de Sitter space in -dimensions and a dual conformal field theory in a euclidean space in -dimensions.…
Correlation functions of sourced gravitational waves in inflationary scalar vector models. A symmetry based approach
Juan P. Beltrán Almeida, Josué Motoa-Manzano, César A. Valenzuela-Toledo
We use conformal symmetry to constrain the shape of inflationary correlators in the presence of long-lived vector field perturbations. Applying conformal Ward identities, we derive…
de Sitter symmetries and inflationary correlators in parity violating scalar-vector models
Juan P. Beltrán Almeida, Josué Motoa-Manzano, César A. Valenzuela-Toledo
In this paper we use conformal field theory techniques to constrain the form of the correlations functions of an inflationary scalar-vector model described by the interaction term…
