Quintom cosmologies with arbitrary potentials
Ruth Lazkoz, Genly León, Israel Quiros
In this paper we investigate quintom cosmologies with arbitrary potentials from the dynamical systems perspective. The dynamical systems analysis is complete in the sense that it i…
Quintessence models of Dark Energy with non-minimal coupling
Tame Gonzalez, Genly Leon, Israel Quiros
We explore quintessence models of dark energy which exhibit non-minimal coupling between the dark matter and the dark energy components of the cosmic fluid. The kind of coupling ch…
A Model of the Universe including dark Energy
Rolando Cardenas, Tame Gonzalez, Osmel Martin +1
In this work we explore a model of the universe in which dark energy is modelled explicitely with both a dynamical quintessence field (with a double exponential self-interaction po…
Modelling dark energy with quintessence and a cosmological constant
Rolando Cardenas, Tame Gonzalez, Osmel Martin +1
In this talk 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 confi…
Comments on the paper astro-ph/0103335 by C Rubano and P Scudellaro
Rolando Cardenas, Osmel Martin, Israel Quiros
We briefly comment on a paper by Rubano and Scudellaro [astro-ph/0103335] where they found general exact solutions for two classes of exponential potentials in a scalar field model…
