Scalar QED Action Density and Schwinger Pair Production in (A)dS_2
Sang Pyo Kim
We review the one-loop effective action in scalar QED and the Schwinger effect in a uniform electric field in a two-dimensional (anti-) de Sitter space. The Schwinger effect has a…
Schwinger Effect in (A)dS and Charged Black Hole
Sang Pyo Kim
In an (Anti-) de Sitter space and a charged black hole the Schwinger effect is either enhanced by the Hawking radiation or suppressed by the negative curvature. We use the contour…
Schwinger Effect, Hawking Radiation and Gauge-Gravity Relation
Sang Pyo Kim
We present a unified picture for the Schwinger effect and the Hawking radiation and address the gauge-gravity relation and the dS-AdS duality issue at the one-loop level. We propos…
Thermal Interpretation of Schwinger Effect in Near-Extremal RN Black Hole
Sang Pyo Kim, Hyun Kyu Lee, Yongsung Yoon
We propose a thermal interpretation of the Schwinger effect for charged scalars and spinors in an extremal and near-extremal Reissner-Nordström (RN) black hole. The emission of cha…
