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…
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…
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…
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…
