Scaling solutions in three-form cosmology
Vitor da Fonseca, Bruno J. Barros, Tiago Barreiro +1
A hybrid three-form model of dark energy is developed in order to identify scaling solutions, a long-sought feature in three-form cosmology. Exploiting Hodge dualities, the theory…

Non-canonical 3-form dark energy
Vitor da Fonseca, Bruno J. Barros, Tiago Barreiro +1
In this study, we meticulously construct a 3-form Lagrangian designed to mimic the dynamics of both dust matter in the past and dark energy driving the acceleration in the present…

Relaxing cosmological constraints on current neutrino masses
Vitor da Fonseca, Tiago Barreiro, Nelson J. Nunes
We show that a mass-varying neutrino model driven by scalar field dark energy relaxes the existing upper bound on the current neutrino mass to eV. We extend the…
