Classical constant electric fields and the Schwinger effect in de Sitter
Mar Bastero-Gil, Paulo B. Ferraz, António Torres Manso, Lorenzo Ubaldi, Roberto Vega-Morales
Izvirni znanstveni članek
Oznake: Schwingerjev pojav;Schwinger effect;de Sitter space;magnetogenesis;
We study constant classical electric fields and the Schwinger effect in de Sitter space, with potential implications for magnetogenesis and inflationary dark matter production. Treating the photon as a dynamical field, we show that sustaining a constant electric field in de Sitter requires a tachyon ...

Schwinger current in de Sitter space
Mar Bastero-Gil, Paulo B. Ferraz, António Torres Manso, Lorenzo Ubaldi, Roberto Vega-Morales
Izvirni znanstveni članek
Oznake: schwinger;de Sitter;dark matter;magnetogenesis;
We study classical background electric fields and the Schwinger effect in de Sitter space. We show that a constant electric field in de Sitter requires the photon to have a tachyonic mass proportional to the Hubble scale. This has physical implications for the induced Schwinger current that affect i ...

Recent endeavoring in biosurface and biointerface analysis with kinetic electrons and ions
Oscar Malvar, Giacomo Ceccone, Paulina Rakowska, Miran Mozetič, Teresa Pinheiro, Miguel Manso-Silván
Pregledni znanstveni članek
Oznake: spektromikroskopija;biointerface analysis;ion spectromicroscopy;
Research in the field of biointerfaces is currently expanding because of continuous scientific demands stemming from different areas of biology and biomedicine. The most challenging questions require new technological advancements, often emerging from apparently distant disciplines, such as vacuum s ...
