Schwinger Effect, Hawking Radiation, and Unruh Effect

摘要

We revisit the Schwinger effect in de Sitter, anti-de Sitter spaces andcharged black holes, and explore the interplay between quantum electrodynamicsand the quantum gravity effect at one-loop level. We then advance a thermalinterpretation of the Schwinger effect in curved spacetimes. Finally, we showthat the Schwinger effect in a near-extremal black hole differs from Hawkingradiation of charged particles in a non-extremal black hole and is factorizedinto those in an anti-de Sitter space and a Rindler space with the surfacegravity for acceleration.
