Sweeping away the monopole problem

    Research output: Contribution to journalArticle


    We propose a new solution to the cosmological monopole problem in which domain walls sweep away the magnetic monopoles and subsequently decay. The solution does not require extensive fine-tuning or model building; it works for the prototype SU(5) grand unification model. More generally, it shows that defect interactions can lead to “defect erasure” in phase transitions and that this can be relevant to early universe physics.
