Formation of Magnetic Monopoles in Hot Gauge Theories
In the non-inflationary Big Bang scenario, magnetic monopoles formed at the phase transition of the Grand Unified Theory (GUT) lead to a severe cosmological problem, because their energy density would be so high that the universe would have collapsed under its own weight a long time ago. This problem is famously solved by inflation, provided that the temperature of the universe never reaches th...
متن کاملThree Dimensional Gauge Theories and Monopoles
The coulomb branch of N = 4 supersymmetric Yang-Mills gauge theories in d = 2 + 1 is studied. A direct connection between gauge theories and monopole moduli spaces is presented. It is proposed that the hyper-Kähler metric of supersymmetric N = 4 SU(N) Yang-Mills theory is given by the charge N centered moduli space of BPS monopoles in SU(2). The theory is compared to N = 2 supersymmetric Yang-M...
متن کاملThree-Dimensional Gauge Theories and ADE Monopoles
We study three-dimensional N = 4 gauge theories with product gauge groups constructed from ADE Dynkin diagrams. One-loop corrections to the metric on the Coulomb branch are shown to coincide with the metric on the moduli space of wellseperated ADE monopoles. We propose that this correspondence is exact. Introduction There exists a correspondence between three-dimensional gauge theories and mono...
متن کاملMagnetic Monopoles in Grand Unified Theories
We suggest that the magnetic monopoles predicted by grand unified theories would not be produced in significant numbers if electromagnetic gauge invariance is spontaneously broken when the temperature T is greater than Tc 2 1 TeV. A model possessing this behavior is displayed and the cosmological implications are discussed. Submitted to Physical Review Letters * Work supported by the Department...
متن کاملMagnetic Monopoles, Fiber Bundles, and Gauge Fields
The reports in this monograph have shown great enthusiasm and exuberance for the unification of various interactions through the concept of gauge fields. I would like to emphasize a point that has not yet been explicitly stated by any of the other authors: gauge fields are deeply related to some profoundly beautiful ideas of contemporary mathematics, ideas that are the driving forces of part of...
