In this work, we propose a new dark energy cosmological model, by considering a new quintom scenario which is based on the superposition between a quintessence scalar field and a noncanonical scalar field, both nonminimally coupled with cubic self-interaction terms. Considering that the two scalar fields of the quintom construction are nonminimally coupled in an independent manner with cubic self-interactions terms in the corresponding action, we have analyzed the dynamical features of the present model in the phase-space. By performing a dynamical system analysis in the case of exponential potentials, we have analyzed the structure of the phase-space, obtaining different possible constraints for the parameters of the model which correspond to distinct evolution scenarios.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
