ACCELERATING UNIVERSES WITH SCALING DARK MATTER
Open accessAbstract
Friedmann–Robertson–Walker universes with a presently large fraction of the energy density stored in an X-component with w X <-1/3, are considered. We find all the critical points of the system for constant equations of state in that range. We consider further several background quantities that can distinguish the models with different w X values. Using a simple toy model with a varying equation of state, we show that even a large variation of w X at small redshifts is very difficult to observe with d L (z) measurements up to z~1. Therefore, it will require accurate measurements in the range 1<z<2 and independent accurate knowledge of Ω m,0 (and/or Ω X,0 ) in order to resolve a variable w X from a constant w X .

In this construction, a single scalar field drives both late-time acceleration and ekpyrotic smoothing at the background level, while the spin-torsion sector supplies the repulsive ρs ∝ a^-6 contribution that regulates the high-density regime, instead of introducing separate ingredients for each phase.
“In this restricted sense the construction is a direct extension of familiar quintessence dynamics [31,32]: a single scalar field drives both late-time acceleration and ekpyrotic smoothing at the background level, while the spin-torsion sector supplies the repulsive ρ s ∝ a -6 contribution that regulates the high-density regime, instead of introducing separate ingredients for each phase.”

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.
