Spinor Particle Creation in Near Extremal Reissner-Nordstrom Black Holes

TL;DR

This paper investigates spinor particle pair production near near-extremal Reissner-Nordstrom black holes, deriving production rates and demonstrating consistency with dual conformal field theory predictions, supporting cosmic censorship.

Contribution

It provides a closed-form expression for spinor pair production rates in near-extremal black holes and links gravitational results with dual CFT calculations.

Findings

Pair production rate derived explicitly in the near extremal limit.

Absorption cross section ratio matches dual CFT predictions.

Cosmic censorship is supported by the pair production process.

Abstract

The pair production of spinor particles, which can be captured by the solution of the Dirac equation with an appropriate boundary condition, in charged black holes is investigated. We obtain the closed form of the production rate in the near extremal limit of the Reissner-Nordstrom black holes. The cosmic censorship conjecture is seemingly guaranteed by the pair production process. Moreover, the absorption cross section ratio and retarded Green's functions of the spinor fields calculated from the gravity side match well with those of spinor operators in the dual CFT side.
