Recent progress in the preheating phenomena for inflationary cosmology is reviewed. We first discuss estimates of the preheating time scale and particle production at the early stages of parametric amplification within the Mathieu and Lam'e approximations and we analyze their precision and limitations. The necessity of self-consistent calculations including the non-linearity of the field theory equations in an energy conserving scheme is stressed. The large N calculations including the field back-reaction are reviewed. For spontaneously broken theories the issue of symmetry restoration is analyzed. A discussion of the possibility and criterion for symmetry restoration is presented.

  1. Reheating constraints to modulus mass for single field inflationary models

    astro-ph.CO 2019-08 reject novelty 4.0 of 10

    A scale-counting argument linking modulus mass to reheating parameters yields quoted bounds m_chi >~ 10^12 to 10^15 GeV that are not supported by the printed equations.
