# Symmetries of inflationary magnetogenesis and the plasma initial conditions

@article{Giovannini2012SymmetriesOI, title={Symmetries of inflationary magnetogenesis and the plasma initial conditions}, author={Massimo Giovannini}, journal={Physical Review D}, year={2012}, volume={86}, pages={103009} }

As soon as the geometry expands quasi-exponentially the plasma sources are customarily tuned to zero as if the duration of the inflationary phase was immaterial for the gauge field fluctuations at large-scale. The serendipitous disappearance of the plasma (or even the partial neglect of its effects) depends on the symmetries of the system which are, in four space-time dimensions and in the simplest Abelian case, the invariance under Weyl rescaling and the electromagnetic duality symmetry. The…
