Can slow roll inflation induce relevant helical magnetic fields?
Ruth Durrer, Lukas Hollenstein, Rajeev Kumar Jain
We study the generation of helical magnetic fields during single field inflation induced by an axial coupling of the electromagnetic field to the inflaton. During slow roll inflati…

Primordial features due to a step in the inflaton potential
Dhiraj Kumar Hazra, Moumita Aich, Rajeev Kumar Jain +2
Certain oscillatory features in the primordial scalar power spectrum are known to provide a better fit to the outliers in the cosmic microwave background data near the multipole mo…
