Dynamics of dark energy in a scalar-vector-torsion theory
Manuel Gonzalez-Espinoza, Giovanni Otalora, Yoelsy Leyva +1
We study the cosmological dynamics of dark energy in a scalar-vector-torsion theory. The vector field is described by the cosmic triad and the scalar field is of the quintessence t…
Effective dark energy through spin-gravity coupling
Giovanni Otalora, Emmanuel N. Saridakis
We investigate cosmological scenarios with spin-gravity coupling. In particular, due to the spin of the baryonic and dark matter particles and its coupling to gravity, they probe a…
Revisiting gravity's rainbow: Inflation and primordial fluctuations
Yoelsy Leyva, Giovanni Otalora
We study inflation and the generation of primordial fluctuations in gravity's rainbow. We calculate the cosmological perturbations and then the scalar and tensor primordial…
