Evolution of density perturbations in double exponential quintessence models
Tame Gonzalez, Rolando Cardenas, Israel Quiros +1
In this work we investigate the evolution of matter density perturbations for quintessence models with a self-interaction potential that is a combination of exponentials. One of th…
Time-like vs Space-like Extra Dimensions
Israel Quiros
Higher-dimensional theories with time-like and space-like extra dimensions are compared both from the conceptual and from the phenomenological points of view. In this context causa…
Exact models with non-minimal interaction between dark matter and (either phantom or quintessence) dark energy
Tame Gonzalez, Israel Quiros
A method for deriving Friedmann-Robertson-Walker (FRW) solutions developed in Int. J. Mod. Phys. D{\bf 5}(1996)71-84, is generalized to account for models with non-minimal coupling…
Causality and Unitarity Are Not Violated in Space-Times with an Additional Compact Time-like Dimension
Israel Quiros
The hypothesis that the causal properties of space-time, as well as other properties of physical systems like unitarity, charge conservation, etc., might be decided by the higher d…
Dynamics of Quintessence Models of Dark Energy with Exponential Coupling to the Dark Matter
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…
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…
