Magnetic monopoles in field theory and cosmology. | LitMetric

Magnetic monopoles in field theory and cosmology.

Philos Trans A Math Phys Eng Sci

Department of Physics, Imperial College London, Prince Consort Road, London SW7 2AZ, UK.

Published: December 2012

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.
