Generation of scale invariant magnetic fields in bouncing universes
L. Sriramkumar, Kumar Atmjeet, Rajeev Kumar Jain
We consider the generation of primordial magnetic fields in a class of bouncing models when the electromagnetic action is coupled non-minimally to a scalar field that, say, drives…
Helical cosmological magnetic fields from extra-dimensions
Kumar Atmjeet, T. R. Seshadri, Kandaswamy Subramanian
We study the inflationary generation of helical cosmological magnetic fields in a higher-dimensional generalization of the electromagnetic theory. For this purpose, we also include…
Cosmological Magnetogenesis From Extra-dimensional Gauss Bonnet Gravity
Kumar Atmjeet, Isha Pahwa, T. R. Seshadri +1
Generation of primordial magnetic fields during inflation typically requires the breaking of conformal invariance of the Electromagnetic action. In this paper this has been achieve…
