Generalizing Holographic Superconductors

We consider a family of holographically dual models of superconductivity to test the robustness of holographic superconductor models in general. Following the treatment of Hartnoll et al. and Albrecht et al., we introduce the basic holographic model and then develop a family of similar models by varying a parameter in the spacetime metric of the holographic theory. We then calculate several observables and compare with actual superconductor observables. This helps determine whether these holographic models actually explain superconductivity or if the agreement between the theories and experiment is a coincidence.
