On the non-Gaussian correlation of the primordial curvature perturbation with vector fields
Rajeev Kumar Jain, Martin S. Sloth
We compute the three-point cross-correlation function of the primordial curvature perturbation generated during inflation with two powers of a vector field in a model where conform…
Cosmological Ohm's law and dynamics of non-minimal electromagnetism
Lukas Hollenstein, Rajeev Kumar Jain, Federico R. Urban
The origin of large-scale magnetic fields in cosmic structures and the intergalactic medium is still poorly understood. We explore the effects of non-minimal couplings of electroma…
Consistency relation for cosmic magnetic fields
Rajeev Kumar Jain, Martin S. Sloth
If cosmic magnetic fields are indeed produced during inflation, they are likely to be correlated with the scalar metric perturbations that are responsible for the Cosmic Microwave…
Generation of helical magnetic fields from inflation
Rajeev Kumar Jain, Ruth Durrer, Lukas Hollenstein
The generation of helical magnetic fields during single field inflation due to an axial coupling of the electromagnetic field to the inflaton is discussed. We find that such a coup…
