    Primordial Dark Energy from a Condensate of Spinors in a 5D Vacuum by Pablo Alejandro Sánchez, Mauricio Bellini

    Published 2013-01-01
    “…We found that the condensate of spinors studied here could be an interesting candidate to explain the presence of dark energy in the early universe. The dark energy density which we are talking about is poured into smaller subhorizon scales with the evolution of the inflationary expansion.…”

    Bianchi Type-I Bulk Viscosity with a DE Cosmological Model by Daba Meshesha Gusu

    Published 2020-01-01
    “…The physical significance of the obtained findings illustrates the dominance of bulk viscosity in early and dominance of dark energy fluid emergences in late. This leads to indicate the presence of bulk viscosity nature more effective in early time rather than late times, and also, it shows the dominance of dark energy in late times which grants the current observational result of the universe. …”

    Modeling Dark Sector in Horndeski Gravity at First-Order Formalism by F. F. Santos, R. M. P. Neves, F. A. Brito

    Published 2019-01-01
    “…Despite this, we show that a de Sitter phase at late-time cosmology can be realized, where the dark energy sector can be identified. The scalar field equation of state tends to the cosmological scenario at present time and allows us to conclude that it can simulate the dark energy in the Horndeski gravity.…”
