Abstract

A crucial ingredient of success of inflationary paradigm rests on explaining the observed classicality of cosmological inhomogeneities despite their quantum origin. Although decoherence provides a partial understanding of this issue, the question of single outcome motivates the analysis using quantum collapse models in cosmological context. We revisit one such recently proposed model of classicalization by spontaneous collapse (Continuous Spontaneous Localization, CSL) to look for possible modifications to tensor power spectra and their implications.
