  We present a new mechanism to condense a scalar field coupled to the
Gauss-Bonnet term. We propose a scenario in which the condensed state will
emerge from the background energy density in the late-Universe. During the
radiation and dust-dominated eras, the energy density of the scalar field,
$\rho_{\varphi}$, decreases at a slower rate than the background density.
Eventually, $\rho_{\varphi}$ dominates over the energy density of dust and the
scalar field could be condensed. In the condensed phase, we have the de Sitter
phase for the universe with $\rho_{\varphi}=3H_0^2M_P^2$. Moreover, we study
the cosmological perturbations of the model and explore predictions of the
model.
