Internal space structure generalization of the quintom cosmological scenario
Luis P. Chimento, Mónica Forte, Ruth Lazkoz +1
We introduce the Lagrangian for a multi-scalar field configuration in a -dimensional internal space endowed with a constant metric and generalize the quintom cosmologic…
Cosmological model with interactions in the dark sector
Luis P. Chimento, Monica Forte, Gilberto M. Kremer
A cosmological model is proposed for the current Universe consisted of non-interacting baryonic matter and interacting dark components. The dark energy and dark matter are coupled…
Bridging geometries and potentials in DBI cosmologies
Luis P. Chimento, Ruth Lazkoz
We investigate the link between the warp function and the potential in DBI cosmologies in connection with the possibility they represent power-law solutions. A prescription is give…
Duality invariance and cosmological dynamics
Luis P. Chimento, Winfried Zimdahl
A duality transformation that interrelates expanding and contracting cosmological models is shown to single out a duality invariant, interacting two-component description of any ir…
