Holographic metals at finite doping

We construct the electron star solution to the model that was recently proposed by Kiritsis and Li in order to describe a holographic superconductor at finite doping. We do so by finding a map between the doped model and the standard undoped one. In this way, we are able to describe the holographic metallic phase at finite doping. In particular, we study the gauge field fluctuations and find the dependence of the electric conductivity on the doping parameter.
