Instability of Anisotropic Cosmological Solutions Supported by Vector Fields
Open accessAbstract
Models with vector fields acquiring a nonvanishing vacuum expectation value along one spatial direction have been proposed to sustain a prolonged stage of anisotropic accelerated expansion. Such models have been used for realizations of early time inflation, with a possible relation to the large scale cosmic microwave background anomalies, or of the late time dark energy. We show that, quite generally, the concrete realizations proposed so far are plagued by instabilities (either ghosts or unstable growth of the linearized perturbations) which can be ultimately related to the longitudinal vector polarization present in them. Phenomenological results based on these models are therefore unreliable.

Each is checked against this paper’s own text: does it say what the citing paper says it does?
When the background is homogeneous and isotropic, inflationary perturbations generally decouple into scalar, vector, and tensor modes.
“When the background is homogeneous and isotropic, inflationary perturbations generally decouple into scalar, vector, and tensor modes (for a review of cosmological perturbation theory see e.g.[34]).”
From Observable effects of anisotropic bubble nucleation (2010) · cites this paper as [34]
Section 3 (page unavailable) says that, for a massive vector field with vanishing background value in an isotropic background, transverse vector perturbations decouple from the other vector-field fluctuations. It does not state that inflationary perturbations generally decouple into scalar, vector, and tensor modes; the example is narrower and does not address tensor modes. (LLM, conf=0.76)

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.
