TL;DR

This paper investigates the thermodynamics and phase transitions of non-Abelian black holes in Gauss-Bonnet gravity with negative cosmological constant, revealing van der Waals behavior and reentrant phase transitions.

Contribution

It provides an analytical study of non-Abelian black holes in Gauss-Bonnet gravity, exploring their phase structure and thermodynamic properties in extended phase space.

Findings

Black hole solutions exhibit van der Waals-like phase transitions.

Reentrant phase transitions are observed in the thermodynamic behavior.

The phase structure aligns with universality classes of known thermodynamic systems.

Abstract

We examine analytical, intrinsically non-Abelian, black holes with SU(2) Yang-Mills matter content. Working in the extended thermodynamics scenario of Lovelock black holes we study the phase structure of a four and a five-dimensional spherically symmetric configuration. We work in Gauss-Bonnet-Einstein-Yang-Mills gravity with negative cosmological constant and use Euclidean methods to explore the thermodynamics of the systems. We observe that the solutions belong to the expected universality class of van der Waals and find a reentrant phase transition.
