Critical points in Lovelock Black Holes

TL;DR

This paper reviews how introducing thermodynamic pressure in Lovelock gravity reveals unique critical points and phase behavior in hyperbolic black holes, highlighting novel thermodynamic phenomena in higher curvature theories.

Contribution

It identifies a special relation among Lovelock couplings that leads to an isolated critical point with non-standard critical exponents for hyperbolic black holes.

Findings

Discovery of a peculiar isolated critical point

Non-standard critical exponents observed

Relation between Lovelock couplings is key

Abstract

We review some of the results obtained by introducing a thermodynamic pressure via the cosmological constant in a class of higher curvature theories known as Lovelock gravity. In particular, we focus on a specific relation between the higher-order Lovelock couplings that introduces a peculiar isolated critical point for hyperbolic black holes characterized by non-standard critical exponents.
