Magnetogenesis in cyclical Universe

- PhysicsClassical and Quantum Gravity

We propose a simple solution to the magnetogenesis problem based on cyclic cosmology. It is demonstrated that magnetic fields, of sufficient strengths to account for the present observational bounds,…

Electric-magnetic duality and the conditions of inflationary magnetogenesis

- Physics
- 2010

The magnetogenesis scenarios triggered by the early variation of the gauge coupling are critically analyzed. In the absence of sources, it is shown that the electric power spectra can be explicitly…

Fluctuations of inflationary magnetogenesis

- Physics
- 2013

This analysis aims at exploring what can be said about the growth rate of magnetized inhomogeneities under two concurrent hypotheses: a phase of quasi-de Sitter dynamics driven by a single inflaton…

Inflationary magnetogenesis without the strong coupling problem

- Physics
- 2013

The simplest gauge invariant models of inflationary magnetogenesis are known to suffer from the problems of either large backreaction or strong coupling, which make it difficult to self-consistently…

Baryogenesis, magnetogenesis and the strength of anomalous interactions

- Physics
- 2021

The production of the hypermagnetic gyrotropy is investigated under the assumption that the gauge coupling smoothly evolves during a quasi-de Sitter phase and then flattens out in the radiation epoch…

Bootstrapping from inflationary magnetogenesis to CMB initial conditions

- Physics
- 2013

The temperature and polarization anisotropies of the cosmic microwave background are analyzed under the hypothesis that the same inflationary seed accounting for protogalactic magnetism also affects…

Symmetries of inflationary magnetogenesis and the plasma initial conditions

- Physics
- 2012

As soon as the geometry expands quasi-exponentially the plasma sources are customarily tuned to zero as if the duration of the inflationary phase was immaterial for the gauge field fluctuations at…

Parameter dependence of magnetized CMB observables

- Physics
- 2009

Predecoupling magnetic fields affect the scalar modes of the geometry and produce observable effects which can be constrained also through the use of current (as opposed to forthcoming) data stemming…

Inflationary susceptibilities, duality, and large-scale magnetic field generation

- Physics
- 2013

We investigate what can be said about the interaction of scalar fields with Abelian gauge fields during a quasi-de Sitter phase of expansion and under the assumption that the electric and the…

Semi-analytical approach to magnetized temperature autocorrelations

The cosmic microwave background (CMB) temperature autocorrelations, induced by a magnetized adiabatic mode of curvature inhomogeneities, are computed with semi-analytical methods. As suggested by the…

Galactic Magnetism: Recent developments and perspectives

▪ Abstract We discuss current observational and theoretical knowledge of magnetic fields, especially the large-scale structure in the disks and halos of spiral galaxies. Among other topics, we…

Primordial magnetic fields and CMB anisotropies

- Chemistry

Large-scale magnetic fields can affect scalar cosmological perturbations whose evolution is described in the conformally Newtonian gauge and within the tight coupling approximation. The magnetized…

Primordial hypermagnetic fields and triangle anomaly

The high-temperature plasma above the electroweak scale $\ensuremath{\sim}100\mathrm{GeV}$ may have contained a primordial hypercharge magnetic field whose anomalous coupling to the fermions induces…

Primordial magnetic fields and nonlinear electrodynamics

- Physics
- 2008

The creation of large scale magnetic fields is studied in an inflationary universe where electrodynamics is assumed to be nonlinear. After inflation ends electrodynamics becomes linear and thus the…

At finite hyperconductivity and finite fermionic density the flux lines of long range hypermagnetic fields may not have a topologically trivial structure. The combined evolution of the chemical…

Topologically non-trivial configurations of the hypermagnetic flux lines lead to the formation of hypermagnetic knots (HK) whose decay might seed the Baryon Asymmetry of the Universe (BAU).HK can be…

Astrophysical objects with negligible resistivity are often threaded by large scale magnetic fields. The generation of these fields is somewhat mysterious, since a magnetic field in a perfectly…

Constraints on pre-big bang parameter space from CMBR anisotropies

The so-called curvaton mechanism -a way to convert isocurvature perturba- tions into adiabatic ones- is investigated both analytically and numerically in a pre-big bang scenario where the role of the…
