Influence of tachyonic instability on the Schwinger effect in Higgs inflation model
Mehran Kamarpour
We investigate the influence of the tachyonic instability on the Schwinger effect in Higgs inflation model.In this work we identify the standard horizon scale and the…
The Schwinger effect by axial coupling in natural inflation model
Mehran Kamarpour
We investigate the process of the Schwinger effect by axial coupling in the natural single-field inflation model in two parts. First we consider the Schwinger effect when the confo…
Magnetogenesis in Higgs inflation
Mehran Kamarpour
We study the generation of magnetic fields in the Higgs inflation model with the axial coupling in order to break the conformal invariance of the Maxwell action and produce strong…
Influence of backreaction of electric fields and Schwinger effect on inflationary magnetogenesis
O. O. Sobol, E. V. Gorbar, M. Kamarpour +1
We study the generation of electromagnetic fields during inflation when the conformal invariance of Maxwell's action is broken by the kinetic coupling of the…
Non-gaussianity in axion N-flation models Quadratic and plus axion potentials
Mehran Kamarpour
In this paper we investigate large non-gaussianity in axion N-flation models, taking account while dynamically a large number of axions begin away from the hilltop region(come down…
