The universe is magnetized on all scales probed so far. On the largest scales, galaxies and
galaxy clusters host magnetic fields at the micro Gauss level coherent on scales up to ten …

We study the generation of primordial black holes (PBH) in a single field inflection point
model of inflation wherein the effective potential is expanded up to the sextic order and the …

In this work we compute the production of magnetic fields in models of axion inflation
coupled to the hypercharge sector of the Standard Model through a Chern-Simons …

The most studied mechanism of inflationary magnetogenesis relies on the time-dependence
of the coefficient of the gauge kinetic term F μν F μν. Unfortunately, only extremely finely …

In this work, we study general features of a regime where gauge fields produced during
inflation cause a strong backreaction on the background evolution and its impact on the …

A bstract We investigate pair creation by an electric field in four-dimensional de Sitter space.
The expectation value of the induced current is computed, using the method of adiabatic …

The coupling of an axion-like particle driving inflation to the Standard Model particle content
through a Chern-Simons term generically sources a dual production of massless helical …

We present detailed forecasts for the constraints on the characteristics of primordial
magnetic fields (PMFs) generated prior to recombination that will be obtained with the …

We study magnetogenesis in axionlike inflation driven by a pseudoscalar field ϕ coupled
axially to the electromagnetic (EM) field (β/M p) ϕ F μ ν F˜ μ ν with dimensionless coupling …

In all inflationary scenarios of primordial black hole (PBH) formation, amplified scalar
perturbations inevitably accompany an induced stochastic gravitational wave background …
