Effect of a magnetic field on Schwinger mechanism in de Sitter spacetime

Effect of a magnetic field on Schwinger mechanism in de Sitter spacetime
She-Sheng Xue, Sang Pyo Kim, Ehsan Bavarsad, Clément Stahl
We investigate the effect of a uniform magnetic field background on scalar QED pair production in a four-dimensional de Sitter spacetime (${\mathrm{dS}}_{4}$). We obtain a pair production rate which agrees with the known Schwinger result in the limit of Minkowski spacetime and with Hawking radiation...
