Schwinger Current in de Sitter Space
Mar Bastero-Gil, Paulo B. Ferraz, António Torres Manso +2
We study classical background electric fields and the Schwinger effect in de Sitter space. We show that having a constant electric field in de Sitter requires the photon to have a…

Classical constant electric fields and the Schwinger effect in de Sitter
Mar Bastero-Gil, Paulo B. Ferraz, António Torres Manso +2
We study constant classical electric fields and the Schwinger effect in de Sitter space, with potential implications for magnetogenesis and inflationary dark matter production. Tre…

Duality Symmetry and Anomaly for Gravitational Waves in Curved Spacetime
Adrian del Rio, Javier Olmedo, António Torres Manso
The vacuum Einstein equations admit a formulation closely analogous to the source-free Maxwell theory. In particular, the linearized equations exhibit an electric-magnetic duality…
