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…
Gradient expansion formalism for magnetogenesis in the kinetic coupling model
O. O. Sobol, A. V. Lysenko, E. V. Gorbar +1
In order to describe magnetogenesis during inflation in the kinetic coupling model, we utilize a gradient expansion which is based on the fact that only long-wavelength (superhoriz…
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…
Backreaction of electromagnetic fields and the Schwinger effect in pseudoscalar inflation magnetogenesis
O. O. Sobol, E. V. Gorbar, S. I. Vilchinskii
We study magnetogenesis in axionlike inflation driven by a pseudoscalar field coupled axially to the electromagnetic (EM) field with dimensionl…
Spatiotemporal vortex rings in atomic Bose-Einstein condensates
O. G. Chelpanova, Y. I. Kuriatnikov, S. Vilchinskii +1
We investigate spatiotemporal vortex rings with phase dislocation both in space and time. It is demonstrated that these structures naturally appear as a periodical in time edge pha…
