Smooth magnetogenesis
L. Campanelli, A. Marrone
In the Ratra scenario of inflationary magnetogenesis, the kinematic coupling between the photon and the inflaton undergoes a nonanalytical jump at the end of inflation. Using smoot…
Superhorizon magnetic fields
Leonardo Campanelli
[Abridged] We analyze the evolution of superhorizon-scale magnetic fields from the end of inflation till today. Whatever is the mechanism responsible for their generation during in…
On the self-similarity of nonhelical magnetohydrodynamic turbulence
Leonardo Campanelli
We re-analyze the Olesen arguments on the self-similarity properties of freely evolving, nonhelical magnetohydrodynamic turbulence. We find that a necessary and sufficient conditio…
Cosmic magnetization out from the vacuum
Leonardo Campanelli
The large-scale magnetic fields we observe today in galaxies and galaxy clusters could be the result of a pure quantum effect taking place during inflation, to wit, the creation of…
Reply to "Comments on Origin of cosmic magnetic fields"
Leonardo Campanelli
In "L. Campanelli, arXiv:1304.6534 [astro-ph.CO]", we have shown that cosmic magnetic fields are a natural consequence of inflation. Our results have been criticized in the recent…
Origin of Cosmic Magnetic Fields
Leonardo Campanelli
We calculate, in the free Maxwell theory, the renormalized quantum vacuum expectation value of the two-point magnetic correlation function in de Sitter inflation. We find that quan…
