Magnetic fields appear everywhere in the universe. From stars and galaxies, all the way to
galaxy clusters and remote protogalactic clouds, magnetic fields of considerable strength …

We review current ideas on the origin of galactic and extragalactic magnetic fields. We begin
by summarizing observations of magnetic fields at cosmological redshifts and on …

Bringing together the key ideas from nonequilibrium statistical mechanics and powerful
methodology from quantum field theory, this 2008 book captures the essence of …

Magnetic fields in Friedmann universes can experience superadiabatic growth without
departing from conventional electromagnetism. The reason is the relativistic coupling …

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 …

The generation of primordial magnetic seed fields during inflation is studied in a theory
derived from the one-loop vacuum polarization effective action of the photon in a curved …

We explore the generation of large-scale magnetic fields from inflation in teleparallelism, in
which the gravitational theory is described by the torsion scalar instead of the scalar …

We estimate the strength of large-scale magnetic fields produced during inflation in the
framework of Dirac-Born-Infeld (DBI) theories. This analysis is sufficiently general in the …

Magnetic fields are observed on nearly all scales in the Universe, from stars and galaxies up
to galaxy clusters and even beyond. The origin of cosmic magnetic fields is still an open …

It is widely believed that primordial magnetic fields are dramatically diluted by the expansion
of the Universe. As a result, cosmological magnetic fields with residual strengths of …
