Phenomenological holographic model of superconductivity

Abstract

We propose a soft-wall holographic model for describing high-temperature superconductivity. Compared with the existing bottom-up holographic superconductivity models, the proposed approach is more phenomenological. On the other hand, the proposed model is mathematically simpler and has more degrees of freedom for describing the conductivity of real high-temperature superconductors. We construct several examples of such models.
