Thermodynamics of Two Dimensional Black Holes

TL;DR

This paper investigates the thermodynamic properties of two-dimensional black holes, including charged variants, from finite distances, confirming previous results and analyzing their stability.

Contribution

It provides new thermodynamic relations for 2D black holes observed from finite distances and extends analysis to charged Jackiw-Teitelboim black holes.

Findings

Thermodynamic relations are derived for 2D black holes from finite spatial observations.

Results agree with previous methods in certain limits.

Thermodynamic stability of these black holes is analyzed.

Abstract

Thermodynamic relations for a class of 2D black holes are obtained corresponding to observations made from finite spatial distances. We also study the thermodynamics of the charged version of the Jackiw-Teitelboim black holes found recently by Lowe and Strominger. Our results corroborate, in appropriate limits, to those obtained previously by other methods. We also analyze the stability of these black holes thermodynamically.
