Schwinger effect from near-extremal black holes in (A)dS space
Chiang-Mei Chen, Sang Pyo Kim
Abstract
We study the Schwinger effect in near-extremal Reissner-Nordstr\"om black holes with electric and/or magnetic charges in (anti-)de Sitter (AdS) space. The formula for the Schwinger effect takes a universal form for near-extremal black holes with the near-horizon geometry of ${\text{AdS}}_{2}\ifmmode\times\else\texttimes\fi{}{S}^{2}$ and with the proper radii for the ${\text{AdS}}_{2}$ space and the two-sphere ${S}^{2}$, regardless of the asymptotically flat or (A)dS space. The asymptotic AdS boundary enhances and the dS boundary suppresses the Schwinger effect, and the small radius of AdS (dS) space reinforces the enhancement and suppression.
