Vector dark matter production during inflation in the gradient-expansion formalism

A. V. Lysenko, O. O. Sobol, S. I. Vilchinskii

A massive vector field is a highly promising candidate for dark matter in the Universe. A salient property of dark matter is its negligible or null coupling to ordinary matter, wit…

Chirality production during axion inflation

E. V. Gorbar, A. I. Momot, I. V. Rudenok +2

We study the generation of the chiral charge during axion inflation where the pseudoscalar inflaton field couples axially to the electromagnetic field through the term $(β/M_p)…

Hypermagnetogenesis from axion inflation: Model-independent estimates

E. V. Gorbar, K. Schmitz, O. O. Sobol +1

Axion inflation coupled to the Standard Model (SM) hypercharge gauge sector represents an attractive scenario for the generation of primordial hypermagnetic fields. The description…

Gauge-field production during axion inflation in the gradient expansion formalism

E. V. Gorbar, K. Schmitz, O. O. Sobol +1

We study the explosive production of gauge fields during axion inflation in a novel gradient expansion formalism that describes the time evolution of a set of bilinear electromagne…

Influence of backreaction of electric fields and Schwinger effect on inflationary magnetogenesis

O. O. Sobol, E. V. Gorbar, M. Kamarpour +1

We study the generation of electromagnetic fields during inflation when the conformal invariance of Maxwell's action is broken by the kinetic coupling of the…

Anomaly-driven inverse cascade and inhomogeneities in a magnetized chiral plasma in the early Universe

E. V. Gorbar, I. Rudenok, I. A. Shovkovy +1

By making use of a simple model that captures the key features of the anomalous Maxwell equations, we study the role of inhomogeneities on the evolution of magnetic fields in a chi…
