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…

Wilson renormalization group and improved perturbation theory
M. Bonini, M. Simionato
We discuss a resummed perturbation theory based on the Wilson renormalization group. In this formulation the Wilsonian flowing couplings, which generalize the running coupling, ent…
