We study the generation of large scale primordial magnetic fields by a cosmological phase transition during the radiation dominated era. The setting is a theory of N charged scalar fields coupled to an abelian gauge field, that undergoes a phase transition at a critical temperature much larger than the electroweak scale. The dynamics after the transition features two distinct stages: a spinodal regime dominated by linear long-wavelength instabilities, and a scaling stage in which the non… Expand
Gravitational waves as cosmological probes for new physics between the electroweak and the grand-unification scale
Relic gravitational waves, generated by strongly first-ord er phase transitions in the early Universe, can serve as cosmological probes for new physics b eyond the Standard Model. We investigateExpand
The Observational Consequences of Primordial Fields
The research presented in this thesis concerns three main topics. First, we investigate the presence of large scale magnetic fields in the universe. We focus on the possibility that they haveExpand

TLDR
If at an early stage of the evolution of the Universe the gauge symmetry of electromagnetism was spontaneously broken, an electric charge asymmetry would develop and be large enough to seed the observed magnetic fields in galaxies via a protogalactic dynamo. Expand
