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…
Symmetry relating Gravity with Antigravity: A possible resolution of the Cosmological Constant Problem?
Israel Quiros
I discuss possible implications a symmetry relating gravity with antigravity might have for smoothing out of the cosmological constant puzzle. For this purpose, a very simple model…
New exact cosmological solutions to Brans-Dicke gravity with a self-interacting scalar-field
Olga Arias, Israel Quiros
We derive a new parametric class of exact cosmological solutions to Brans-Dicke theory of gravity with a self-interacting scalar field and a barotropic perfect fluid of ordinary ma…
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…
Scale Invariant Kaluza-Klein Theory and the Fate of the Gravitational Collapse
Israel Quiros
Pushing forward the similitudes between the gravitational collapse and the expansion of the universe (in the reversed sense of time), it should be expected that, during the collaps…
