Large scale magnetogenesis from a non-equilibrium phase transition in the radiation dominated era
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…
Magnetic field generation from non-equilibrium phase transitions
D. Boyanovsky, H. J de Vega, M. Simionato
We study the generation of magnetic fields during the stage of particle production resulting from spinodal instabilities during phase transitions out of equilibrium. The main premi…
The Landau Pole at Finite Temperature
H. J. de Vega, M. Simionato
We study the Landau pole in the lambda phi^4 field theory at non-zero and large temperatures. We show that the position of the thermal Landau pole Lambda_L(T) is shifted to higher…
Relaxation Near the Critical Point
Michele Simionato
I present an analysis of the relaxation rate for long-wavelength fluctuations of the order parameter in an O(N) scalar theory near the critical point. Our motivation is to model th…
Relaxing Near the Critical Point
D. Boyanovsky, H. J. de Vega, M. Simionato
Critical slowing down of the relaxation of the order parameter is relevant both in early the universe and in ultrarelativistic heavy ion collisions. We study the relaxation rate of…
Non-equilibrium quantum plasmas in scalar QED: photon production, magnetic and Debye masses, and conductivity
D. Boyanovsky, H. J. de Vega, M. Simionato
We study the generation of a non-equilibrium plasma in scalar QED with N charged scalar fields through spinodal instabilities in the case of a super cooled second order phase trans…
