Abstract

In this paper we consider a unique model of inflation where the universe undergoes rapid asymmetric oscillations, each cycle lasting $\ensuremath{\sim}{10}^{6}$ Planck times. Over many, many cycles the space-time expands to mimic the standard inflationary scenario. Moreover, these rapid oscillations leave a distinctive periodic signature in $\mathrm{ln}k$ in the primordial power spectrum, where $k$ denotes the comoving scale. Although the cyclic-inflation model contains additional parameters as compared to the standard power-law spectrum, the improvement to the fit of the 7-year WMAP data is significant.

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.
