We also apply our bounds to monopoles produced by the primordial magnetic fields themselves through the Schwinger effect, and derive additional conditions for the survival of the primordial fields.

WebThe Schwinger Effect: non-perturbative particle production from vacuum The quantum vacuum is unstable under the influence of an external electric field, as the virtual electron-positron dipole pairs can gain energy from the external field. Webformulation of the Schwinger formalism based on Schwinger’s proper-time representation of propagators in an external eld. Besides new methods for calculating particle production in an external eld, this approach provides a great deal of intuition on the spatio-temporal development of the production process. croft community school dh9 8pr
