Abstract

In this paper, we propose the non-linear Born–Infeld scalar field and canonical scalar field dark energy models with the potential \(\frac{\lambda }{4}( {\phi ^2 - \sigma ^2 })^2 + V_0\), which admits late time de Sitter attractor solution. The attractor solution corresponds to an equation of state ω_φ → − 1 and a cosmic density parameter Ω_φ → 1, which are important features for a dark energy model that can meet the current observations. dark energy; canonical scalar field, non-linear Born–Infeld type scalar field, attractor solution.
