Primordial magnetic fields from cosmological phase transitions
D. Boyanovsky, H. J. de Vega, M. Simionato
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…

Out of Equilibrium Fields in Self-consistent Inflationary Dynamics. Density Fluctuations
D. Boyanovsky, H. J. de Vega
The physics during the inflationary stage of the universe is of quantum nature involving extremely high energy densities. Moreover, it is out of equilibrium on a fastly expanding d…

Self-Consistent Dynamics of Inflationary Phase Transitions
D. Boyanovsky, D. Cormier, H. J. de Vega +2
The physics of the inflationary universe requires the study of the out of equilibrium evolution of quantum fields in curved spacetime. We present the evolution for both the geometr…
