Quantum kinetic approach to the Schwinger production of scalar particles in an expanding universe
Anastasia V. Lysenko, Oleksandr O. Sobol
We study the Schwinger pair creation of scalar charged particles by a homogeneous electric field in an expanding universe in the quantum kinetic approach. We introduce an adiabatic…
Bound states of a one-dimensional Dirac equation with multiple delta-potentials
V. P. Gusynin, O. O. Sobol, A. V. Zolotaryuk +1
Two approaches are developed for the study of the bound states of a one-dimensional Dirac equation with the potential consisting of -function centers. One of these uses the…
Axion inflation in the strong-backreaction regime: decay of the Anber-Sorbo solution
Richard von Eckardstein, Marco Peloso, Kai Schmitz +2
Axion inflation coupled to Abelian gauge fields via a Chern-Simons-like term of the form represents an attractive inflationary model with a rich phenomenology, includ…
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…
