Quintom phase-space: beyond the exponential potential
Genly Leon, Yoelsy Leyva, J. Socorro
We investigate the phase-space structure of the quintom dark energy paradigm in the framework of spatially flat and homogeneous universe. Considering arbitrary decoupled potentials…

Evolution of density perturbations in double exponential quintessence models
Tame Gonzalez, Rolando Cardenas, Israel Quiros +1
In this work we investigate the evolution of matter density perturbations for quintessence models with a self-interaction potential that is a combination of exponentials. One of th…
