Magnetic monopoles in field theory and cosmology.
نویسنده
چکیده
The existence of magnetic monopoles is predicted by many theories of particle physics beyond the standard model. However, in spite of extensive searches, there is no experimental or observational sign of them. I review the role of magnetic monopoles in quantum field theory and discuss their implications for particle physics and cosmology. I also highlight their differences and similarities with monopoles found in frustrated magnetic systems.

This Theme Issue reports papers presented at a Discussion Meeting intended to bring together theorists and experimentalists working on magnetic charge carriers, or monopoles, in both natural and artificially nanostructured spin ice lattices, and to explore related topics on Berry phase physics and domain wall motion and a possible solid-state/cosmology interface in these systems. The Discussion...
متن کاملMagnetic Monopoles, Duality, and Supersymmetry
These notes present a pedagogical introduction to magnetic monopoles and exact electromagnetic duality in supersymmetric gauge theories. They are based on lectures given at the 1995 Trieste Summer School in High Energy Physics and Cosmology and at the 1995 Busstepp Summer School at Cosener’s House.
متن کاملMonopoles, Antimonopoles and Vortex Rings
Introduction Defects, classical solutions of spontaneously broken gauge theories, where the Higgs field vanishes at points, lines or surfaces, are relevant in particle physics and cosmology. Monopoles, for instance, represent zero-dimensional defects, vortex solutions or strings are associated with one-dimensional defects, domain walls represent two-dimensional defects. Here we present new clas...
متن کاملLectures on Cosmic Topological Defects
These lectures review certain topological defects and aspects of their cosmology. Unconventional material includes brief descriptions of electroweak defects, the structure of domain walls in non-Abelian theories, and the spectrum of magnetic monopoles in SU(5) Grand Unified theory.
متن کاملBasics of inflationary cosmology
The early stages of the universe evolution are discussed according to the hot big bang model and the grand unified theories. The shortcomings of big bang are summarized and their resolution by inflationary cosmology is sketched. Cosmological inflation, the subsequent oscillation and decay of the inflaton field, and the resulting reheating of the universe are studied in some detail. The density ...
