Equilibrium and non-equilibrium properties of the QGP in a magnetic field: a holographic approach

Abstract

This manuscript reviews recent theoretical progress on the understanding of the quark gluon plasma in a magnetic field that I presented on the conference Hot Quarks 2016, held at South Padre Island, Texas, USA, 12-17 September 2016. It is shown that, using a holographic bottom-up Einstein-Maxwell-Dilaton model, one can have a good quantitative agreement with Lattice data for QCD equation of state and Polyakov loop with nonzero magnetic field. I also present results for the anisotropic shear viscosity ratio $\eta_{\parallel}/\eta_{\perp}$, with the conclusion that $\eta_{\parallel}<\eta_{\perp}$ for $B>0$.
