Exploring The Multiverse with Topological Defects

Zhang, Jun.

Abstract: Inflationary cosmology suggests a nontrivial spacetime structure on scales beyond our observable universe, the multiverse. Based on the observation that topological defects and vacuum bubbles can spontaneously nucleate in a de Sitter like inflating space, we explore two different aspects of the multiverse model in this thesis. Hence the main body of this study consists of two parts. In t... read more
