On the magnetic field spectrum and its fluctuations in a primeval cold plasma in thermal equilibrium

Francisco Caruso, Vitor Oguri, Felipe Silveira


Magnetic fluctuations in a non-magnetized gaseous plasma is revisited and calculated without any approximation, based on the fluctuation-dissipation theorem. Also the simultaneous dependence of this intensity on the plasma and on the collisional frequencies is discussed. Finally, the total emitted plasma energy is compared to the Stefan-Boltzmann law of a pure black-body.
