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…
Cosmology and fundamental physics with the Euclid satellite
Luca Amendola, Stephen Appleby, David Bacon +60
Euclid is a European Space Agency medium class mission selected for launch in 2019 within the Cosmic Vision 2015-2025 programme. The main goal of Euclid is to understand the origin…
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…
