Gravitational wave physics can probe theories that extend beyond general relativity. Motivated by recent attention on the Kalb-Ramond field as a dark matter candidate, in this …
In this paper we study some models where non-Abelian gauge vector fields endowed with a SU (2) group representation are the unique source of inflation and dark energy. These …

This paper investigates the cosmological dynamics arising from the interaction between a 2- form field and cold dark matter within a Bianchi I background. Employing a dynamical …
We study the dynamics of dark energy in the presence of a 2-form field coupled to a canonical scalar field ϕ. We consider the coupling proportional to e− μ ϕ/M pl H α β γ H α β γ …
A bstract We embed a new three-form vector multiplet in\(\mathcal {N}\)= 1 supergravity and we show that it can be used to generate dynamically the Hilbert-Einstein term. We then …

In this paper we consider a model based on interacting p-forms and explore some cosmological applications. Restricting to gauge invariant actions, we build a general …
A non-local yet gauge-invariantly massive 2-form model is considered that leads to local and unitary dynamics upon proper gauge-fixing. Since canonical momenta cannot be defined …

In this paper, we investigate the validity of the so-called cosmic no-hair conjecture in the framework of anisotropic inflation models of non-canonical scalar fields non-minimally …

A bstract 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 …
