# Black hole chemistry and holography in generalized quasi-topological gravity

## TL;DR

This paper explores the thermodynamics, phase transitions, and holographic properties of AdS black holes in cubic generalized quasi-topological gravity, revealing new critical behaviors and modifications to viscosity-entropy ratios.

## Contribution

It introduces the study of black hole thermodynamics and phase transitions in cubic generalized quasi-topological gravity, including holographic implications, which is a novel extension of previous work.

## Key findings

- Discovery of new critical behaviors and phase transitions in charged black holes.
- Modification of the viscosity-to-entropy ratio due to cubic curvature terms.
- Analysis of Hawking-Page transitions in higher-dimensional black holes.

## Abstract

We investigate the thermodynamics of AdS black holes in Generalized Quasitopological Gravity with and without electric charge, concentrating on the version of the theory that is cubic in curvature. We study new aspects of Hawking-Page transitions that occur for these black holes. Working within the framework of black hole chemistry, we find a variety of familiar and new critical behaviour and phase transitions in four and higher dimensions for the charged black holes. We also consider some holographic aspects of our work, demonstrating how the ratio of viscosity to entropy is modified by inclusion of these cubic curvature terms.
