We propose a dark energy density based on the Gauss–Bonnet four-dimensional invariant and its modification. This model avoids the necessity of introducing the black hole limit to define the holographic density, since it can be considered as a nonsaturated regime. This allows to describe the dark energy with an equation of state (EoS) and Hubble parameter behaving in a way that can be adjusted very well to recent observations. The model presents quintom behavior without any future fine-time singularities.
