TL;DR

This paper investigates the phase diagrams of a holographic s+p model in five-dimensional Gauss-Bonnet gravity, analyzing how the Gauss-Bonnet term influences the system's thermodynamic phases.

Contribution

It provides the first detailed analysis of the P-T and Δ-T phase diagrams of the holographic s+p model with Gauss-Bonnet corrections, highlighting the effects of the Gauss-Bonnet term.

Findings

Gauss-Bonnet term significantly affects phase transition boundaries.

Different pressure definitions lead to comparable P-T phase diagrams.

Phase diagrams vary with the Gauss-Bonnet coefficient.

Abstract

In this paper, we study the holographic s+p model in 5-dimensional bulk gravity with the Gauss-Bonnet term. We work in the probe limit and give the $\Delta$-T phase diagrams at three different values of the Gauss-Bonnet coefficient to show the effect of the Gauss-Bonnet term. We also construct the P-T phase diagrams for the holographic system using two different definitions of the pressure and compare the results.
