摘要：
We investigate the origin and evolution of primordial electric and magnetic fields in the early universe, when the expansion is governed by a cosmological constant Lambda(0). Using the gravitoelectromagnetic inflationary formalism with A(0) = 0, we obtain the power of spectrums for large-scale magnetic fields and the inflaton field fluctuations during inflation. A very important fact is that our formalism is naturally non-conformally invariant. (C) 2009 Elsevier B.V. All rights reserved.
