From Inflation
arXiv:hep-ph/9501396 · doi:10.1016/0920-5632(95)00473-M
Abstract
An inflationary scenario that leads to today is presented. An epoch of `old' inflation during which the smoothness and horizon problems are solved is followed by a shortened epoch of `new' inflation. Old inflation exits through the nucleation of a single bubble, leading to negative spatial curvature on slices of constant cosmic time. We calculate the spectrum of density perturbations in such a scenario.
