TL;DR
This paper reviews holographic modeling of quark-gluon plasma at finite temperature and baryon density, showing good agreement with lattice QCD and predicting suppressed baryon diffusion at higher chemical potentials.
Contribution
It introduces a bottom-up Einstein-Maxwell-Dilaton holographic model that accurately reproduces thermodynamic and transport properties of the quark-gluon plasma at finite baryon density.
Findings
Equation of state matches lattice QCD results
Baryon susceptibilities agree with lattice data
Baryon diffusion decreases with increasing chemical potential
Abstract
This is a contribution for the Proceedings of the Conference Hot Quarks 2016, held at South Padre Island, Texas, USA, 12-17 September 2016. I briefly review some thermodynamic and baryon transport results obtained from a bottom-up Einstein-Maxwell-Dilaton holographic model engineered to describe the physics of the quark-gluon plasma at finite temperature and baryon density. The results for the equation of state, baryon susceptibilities, and the curvature of the crossover band are in quantitative agreement with the corresponding lattice QCD results with flavors and physical quark masses. Baryon diffusion is predicted to be suppressed by increasing the baryon chemical potential.
