Two-scalar-field model for the interaction of dark energy and dark matter

Orfeu Bertolami, Pedro Carrilho, Jorge Páramos

In this paper, we study the effects of an interaction between dark matter and dark energy through a two scalar field model with a potential $V(\varphi ,\chi )=e^{-\lambda \varphi }P(\varphi ,\chi )$, where $P(\varphi ,\chi )$ i…
