Non-Gaussian features of primordial magnetic fields in power-law inflation
Leonardo Motta, Robert R. Caldwell
We show that a conformal-invariance violating coupling of the inflaton to electromagnetism produces a cross correlation between curvature fluctuations and a spectrum of primordial…

Correlation of inflation-produced magnetic fields with scalar fluctuations
Robert R. Caldwell, Leonardo Motta, Marc Kamionkowski
If the conformal invariance of electromagnetism is broken during inflation, then primordial magnetic fields may be produced. If this symmetry breaking is generated by the coupling…
