A bstract The Kalb-Ramond field is an antisymmetric, rank-two tensor field which most
notably appears in the context of string theory, but has largely been unexplored in the …

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 …

We explore the possible advantages of extending the standard Λ CDM model by more
realistic backgrounds compared to its spatially flat Robertson–Walker (RW) spacetime …

We present two families of multi-field potentials that support inflation while satisfying the
refined de Sitter and the distance swampland conjectures. Both families feature Planck …

A bstract We explore the cosmological dynamics of a minimalistic yet generic string-inspired
model for multifield dark energy. Adopting a supergravity four-dimensional viewpoint, we …

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 …

In this paper, we study the late time cosmology of a non-canonical scalar field (k-essence)
coupled to a vector field in a Bianchi-I background. Specifically, we study three cases …

We study a model of two scalar fields with a hyperbolic field space and show that it reduces
to a single-field Dirac-Born-Infeld (DBI) model in the limit where the field space becomes …

In the context of the dark energy scenario, the Einstein Yang-Mills Higgs model in the SO (3)
representation was studied for the first time by M. Rinaldi (see [1]) in a homogeneous and …

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 …
