Quintessence, superquintessence, and observable quantities in Brans-Dicke and nonminimally coupled theories
Open accessAbstract
The different definitions for the equation of state of a nonminimally coupled scalar field that have been introduced in the literature are analyzed. Particular emphasis is made upon those features that could yield an observable way of distinguishing nonminimally coupled theories from general relativity, with the same or with alternate potentials. It is found that some earlier claims that superquintessence, a stage of superaccelerated expansion of the universe, is possible within realistic nonminimally coupled theories are the result of an arguable definition of the equation of state. In particular, it is shown that these previous results do not import any observable consequence, i.e., that the theories are observationally identical to general relativity models and that superquintessence is not more than a mathematical outcome. Finally, in the case of nonminimally coupled theories with coupling $F=1+\ensuremath{\xi}{\ensuremath{\varphi}}^{2}$ and tracking potentials, it is shown that no superquintessence is possible.

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.
