| Abstract: I will argue that the vacuum structure of the standard electroweak model is better viewed as a Hopf fibered three sphere and its topology implies that the model contains confined magnetic monopoles. The Kibble mechanism is then applied to electroweak symmetry breaking to obtain the distribution of magnetic monopoles. The cosmological magnetic field resulting from the monopoles depends on the evolution and may be consistent with blazar lower bounds on the magnetic field strength in large-scale structure voids.
A rigorous analysis of the quantum formation of topological defects will also be discussed with results that can be compared to those using the Kibble-Zurek mechanism. |
