Cosmological Dynamics of a Hybrid Chameleon Scenario

Figure 1

The behavior of the runaway potential (chromatic surface) and the coupling term 𝑒^{𝜅𝛽(𝜙+𝜑)} (the magenta meshed surface) with respect to the two components (𝜙 and 𝜑) of the hybrid scalar field. By increment of the scalar fields, the runaway potential decreases, while the coupling term increases.
