Perturbations of the quintom models of dark energy and the effects on observations
Open accessAbstract
We study in this paper the perturbations of the quintom dark energy model and the effects of quintom perturbations on the current observations. Quintom describes a scenario of dark energy where the equation of state gets across the cosmological constant boundary $w=\ensuremath{-}1$ during evolution. We present a new method to show that the conventional dark energy models based on a single $k$-essence field and perfect fluid cannot act as the quintom due to the singularities and classical instabilities of perturbations around $w=\ensuremath{-}1$. One needs to add extra degrees of freedom for successful quintom model building. There are no singularities or classical instabilities in perturbations of realistic quintom models and they are potentially distinguishable from the cosmological constant. Basing on the realistic quintom models in this paper we provide one way to include the perturbations for dark energy models with parametrized equation of state across $\ensuremath{-}1$. Compared with those assuming no dark energy perturbations, we find that the parameter space which allows the equation of state to get across $\ensuremath{-}1$ will be enlarged, in general, when including the perturbations.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
