Pair production from Reissner-Nordstr\"om-anti-de Sitter black holes

TL;DR

This paper investigates scalar pair production in five-dimensional near extremal Reissner-Nordström-Anti de Sitter black holes, linking gravitational phenomena with holographic dual descriptions in both IR and UV conformal field theories.

Contribution

It provides a comprehensive analysis of pair production rates, absorption cross sections, and their holographic duals in the context of RN-AdS5 black holes, extending understanding of quantum effects in curved spacetime.

Findings

Pair production rate proportional to near horizon parameters.

Absorption cross section ratio matches near horizon predictions.

Holographic dual descriptions in both IR and UV regimes established.

Abstract

We study the pair production of charged scalar particles from the five-dimensional near extremal Reissner- Nordstr\"om-Anti de Sitter (RN-AdS5) black hole. The pair production rate and the absorption cross section ratio in the full spacetime are obtained and are shown to have proportional relation with their counterparts in the near horizon region. In addition, the holographic descriptions of the pair production both in the IR CFT in the near horizon region and the UV CFT at the asymptotic spatial boundary of the RN-AdS5 black hole are analyzed in the AdS2/CFT1and AdS5/CFT4correspondences, respectively. This work gives a complete description of scalar pair production in the near extremal RN-AdS5black hole.
