Primordial Plasma Fluctuations. I. Magnetization of the Early Universe by Dark Aperiodic Fluctuations in the Past Myon and Prior Electron–Positron Annihilation Epoch

摘要

During the past myon and prior electron annihilation epoch of the early universe the electron–positron pair number density was very high as the pairs were in thermal equilibrium with the intense superluminal photons at temperatures kBT?>?1 MeV. With classical plasma fluctuation theory, it is shown that these pairs generate random electric and magnetic fields in the form of collective damped aperiodic fluctuations with very high tera-Gauss strengths on spatial scales greater than cm with a 100% volume filling factor. The associated field decay with time by damping is compensated by their perpetually re-excitation due to the spontaneous emission by the pairs to maintain a lasting fluctuation level.
