Lukewarm inflation and the QCD axion
Paulo B. Ferraz, António Torres Manso, João G. Rosa
We show that a late period of warm inflation, at temperatures just above the QCD scale, can dilute the abundance of the QCD axion produced by the misalignment mechanism, thus avoid…
Lukewarm inflation, primordial black holes and gravitational waves
Paulo B. Ferraz, António Torres Manso, João G. Rosa
We show that a secondary period of warm inflation, at temperatures parametrically below the GUT scale, may not only dilute any unwanted thermal relics formed after reheating but al…
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…
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…
-Inflaton Dark Matter
Antonio Torres Manso, Joao G. Rosa
We present a unified model where the same scalar field can drive inflation and account for the present dark matter abundance. This scenario is based on the incomplete decay of the…
