Production of Topological Defects at the End of Inflation

TL;DR

This paper explores how to reconcile the theories of cosmological inflation with the formation of topological defects like cosmic strings, aiming to unify two historically competing concepts in early universe cosmology.

Contribution

It proposes a framework or mechanism that allows inflation and topological defect formation to coexist in the early universe.

Findings

Cosmological inflation can be compatible with the formation of topological defects.

A specific model or scenario is proposed to reconcile the two phenomena.

The approach addresses longstanding conflicts between inflationary theory and defect formation.

Abstract

Cosmological inflation and topological defects have been considered for a long time, either in disagreement or in competition. On the one hand an inflationary era is required to solve the shortcomings of the hot big bang model, while on the other hand cosmic strings and string-like objects are predicted to be formed in the early universe. Thus, one has to find ways so that both can coexist. I discuss how to reconcile cosmological inflation with cosmic strings.
