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…

First Dark Photon Search Results from the Dandelion Experiment
I. Ourahou, S. Savorgnano, C. Beaufort +9
This paper presents the first results from the Dandelion experiment, a directional detection, which searches for 1 meV dark photon dark matter. We use a spherical mirror to convert…
