Topological defects-such as Domain Walls, cosmic strings, and magnetic monopoles-are expected to appear during a phase transition in the GUT of particle physics. Such monopoles would be the universe's dominant matter during the early universe. However, this is in tension with the fact that monopoles have not been observed. The former is known as the cosmological monopole problem. Different solutions to this problem are known today, with inflation being the most well-known. In this scenario, the universe inflates, dilutes the monopoles, and their density decreases to acceptable levels. Another…mehr

Produktbeschreibung
Topological defects-such as Domain Walls, cosmic strings, and magnetic monopoles-are expected to appear during a phase transition in the GUT of particle physics. Such monopoles would be the universe's dominant matter during the early universe. However, this is in tension with the fact that monopoles have not been observed. The former is known as the cosmological monopole problem. Different solutions to this problem are known today, with inflation being the most well-known. In this scenario, the universe inflates, dilutes the monopoles, and their density decreases to acceptable levels. Another solution was proposed by Dvali, Liu, and Vachaspati in 1997.The main idea is that Domain Walls, generated during the same phase transition, swept away the monopoles before decaying.In general, this solution proposes that defect interactions lead to a defect erasure mechanism. This mechanism has been investigated in a SU(5) grand unified model.
