Integrable models, degenerate horizons and AdS_2 black holes

TL;DR

This paper explores the connection between near extremal Reissner-Nordstrom black holes and the Jackiw-Teitelboim model, demonstrating how asymptotic symmetries reproduce entropy deviations and discussing potential extensions to black hole evaporation.

Contribution

It establishes a link between black hole entropy deviations and the JT model's Virasoro symmetry, providing a new perspective on black hole thermodynamics.

Findings

Virasoro symmetry reproduces entropy deviations

JT model effectively describes near extremal black holes

Potential framework for studying black hole evaporation

Abstract

The near extremal Reissner-Nordstrom black holes in arbitrary dimensions ca be modeled by the Jackiw-Teitelboim (JT) theory. The asymptotic Virasoro symmetry of the corresponding JT model exactly reproduces, via Cardy's formula, the deviation of the Bekenstein-Hawking entropy of the Reissner-Nordstrom black holes from extremality. We also comment how can we extend this approach to investigate the evaporation process.
