The Anti-deSitter/Conformal Field Theory (AdS/CFT) correspondence is a duality relating strongly correlated quantum field theories to classical gravity in one higher dimension. Although discovered in the context of string theory, it has more recently been applied to condensed matter physics, where it offers insight into strongly correlated systems at a quantum critical point. In this talk, I will briefly introduce the AdS/CFT correspondence and indicate the connection to condensed matter physics. I turn to the electron star, a model of a perfect fluid of charged fermions backreating onto the geometry. I will discuss the numerical results obtained by solving the resulting equations of motion. Then, I turn to a description of fermions in curved spacetime, after which I will consider the fermion equations of motion in the electron star background. Finally, as an outlook, I will mention several extensions of this model.
