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…
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…
