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…
Equilibration of the chiral asymmetry due to finite electron mass in electron-positron plasma
A. Boyarsky, V. Cheianov, O. Ruchayskiy +1
We calculate the rate of collisional decay of the axial charge in an ultrarelativistic electron-positron plasma, also known as the chirality flipping rate. We find that contrary to…
Evolution of the Primordial Axial Charge across Cosmic Times
A. Boyarsky, V. Cheianov, O. Ruchayskiy +1
We investigate collisional decay of the axial charge in an electron-photon plasma at temperatures 10 MeV - 100 GeV. We demonstrate that the decay rate of the axial charge is first…
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…
