**Cover Story**(view full-size image): The work "A 3D Phase Space Analysis of Scalar Field Potentials" studies the background evolution of two quintessence scalar field models, namely a potential connecting inflation and dark-energy eras and a newly proposed potential inspired by alpha-attractor models. To analyze these models, we use the formalism of dynamical systems, and for certain specific points, we apply a more sophisticated technique, the center manifold theorem. Interestingly, we find that the two models can be clearly distinguished and constrained. Additionally, a double potential, rather than one, is needed to achieve scaling solutions followed by a late time attractor. We highlight that this is one of few works in literature providing analytical results for an arbitrary scalar field potential. View this paper
