Backreaction from gauge fields produced during inflation
R. Durrer, O. Sobol, S. Vilchinskii
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 spect…
Magnetogenesis in Higgs-Starobinsky inflation
R. Durrer, O. Sobol, S. Vilchinskii
In the framework of mixed Higgs-Starobinsky inflation, we consider the generation of Abelian gauge fields due to their nonminimal coupling to gravity (in two different formulations…
Generation of an electromagnetic field nonminimally coupled to gravity during Higgs inflation
O. O. Sobol, E. V. Gorbar, O. M. Teslyk +1
In the framework of Higgs inflation, we consider the electromagnetic field nonminimally coupled to gravity via the parity-preserving and parity-violating $\propto…
Schwinger production of scalar particles during and after inflation from the first principles
O. O. Sobol, E. V. Gorbar, A. I. Momot +1
By using the first-principles approach, we derive a system of three quantum kinetic equations governing the production and evolution of charged scalar particles by an electric fiel…
Kinetic approach to the Schwinger effect during inflation
E. V. Gorbar, A. I. Momot, O. O. Sobol +1
Using the kinetic approach, we study the impact of the charged particles dynamics due to the Schwinger effect on the electric field evolution during inflation. As a simple model of…
