Lorentz-violating inflationary magnetogenesis
  A non-conformally invariant coupling between the inflaton and the photon in
the minimal Lorentz-violating standard model extension is analyzed. For
specific forms of the Lorentz-violating background tensor, the strong-coupling
and backreaction problems of magnetogenesis in de Sitter inflation with scale
$\sim 10^{16}$GeV are evaded, the electromagnetic-induced primordial spectra of
(Gaussian and non-Gaussian) scalar and tensor curvature perturbations are
compatible with cosmic microwave background observations, and the
inflation-produced magnetic field directly accounts for cosmic magnetic fields.
