A model of the Universe including Dark Energy accounted for by both a Quintessence Field and a (negative

By O Cardenas, Tame Gonzalez, Yoelsy Leiva, Osmel Martin and Israel Quiros


In this work we present a model of the universe in which dark energy is modelled explicitely with both a dynamical quintessence field and a cosmological constant. Our results confirm the possibility of a future collapsing universe (for a given region of the parameter space), which is necessary for a consistent formulation of string theory and quantum field theory. We have also reproduced the measurements of modulus distance from supernovae with good accuracy
