Large-scale energy-density perturbations and inflation

Lyth, D. H.·1985·Physical Review D

Abstract

A first-order differential equation is given for large-scale energy-density perturbations in a Friedmann universe, which expresses the fact that each region of spacetime evolves like a separate Friedmann universe with small spatial curvature (the average curvature is taken to vanish). Using it perturbations generated in an inflationary era are evolved to the present (for sufficiently large scales) with essentially no assumption about intervening eras. The field fluctuations are shown to be essentially quantum mechanical until a few Hubble times after the scale leaves the horizon during the de Sitter era, but probably classical at later times. Full comparison with earlier work is made.

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.
