Holographic Q-picture of Kerr-Newman-AdS-dS Black Hole

TL;DR

This paper proposes a new holographic dual description of Kerr-Newman-AdS-dS black holes based on charge, complementing the existing angular momentum perspective, and supports it with entropy and scattering correlation matches.

Contribution

It introduces an alternative holographic dual for Kerr-Newman-AdS-dS black holes focusing on charge, expanding the understanding of their dual conformal field theories.

Findings

Matching of macroscopic entropy with microscopic counting via Cardy formula

Agreement of real-time correlators in superradiant scattering

Two different holographic descriptions based on angular momentum and charge

Abstract

In this article, we show that a four-dimensional Kerr-Newman-AdS-dS black hole could be described by two different holographic two-dimensional conformal field theories. The first description, in view of the angular momentum, has been well discussed in (arXiv:1006.0157). The other alternative dual picture, however, is somehow overlooked. This new description, in view of the charge, provides another holographic correspondence. This picture again is supported not only by the match of the macroscopic entropy with the counting of microscopic degrees of freedom via the Cardy formula and also by the agreement on the real-time correlator in the superradiant scattering.
