Exact solutions using power law scalar potential in the Saez-Ballester-K-essence like theory
J. Socorro, A. Gil-Ocaranza, Ximena López-Mujica +1
We investigate a K-essence like cosmological model whose scalar-field potential is constructed from a negative power-law Sáez--Ballester potential. By means of a suitable field re…

Power law scalar potential in the Saez-Ballester like theory: Exact solutions in the Bianchi type I case
J. Socorro, A. Gil-Ocaranza, Juan Luis Pérez
We investigate exact anisotropic Bianchi type I cosmological solutions in a generalized S'aez--Ballester--K-essence-like theory containing two interacting scalar fields with quinte…

Dark energy from neutrino interactions in Unimodular Gravity
Alejandro Gil-Ocaranza, Josue De-Santiago, Mauricio Lopez-Hernandez +1
We investigate a dark energy scenario generated by neutrino interactions mediated by a light scalar field, in which finite-temperature corrections induce an effective neutrino mass…
