Physical Review D
We present a dimensionally deconstructed model of an s-wave holographic superconductor. The 2 + 1 dimensional model includes multiple charged Cooper pair fields and neutral exciton fields that have interactions governed by hidden local symmetries. We derive AdS/CFT-like relations for the current and charge density in the model, and we analyze properties of the Cooper pair condensates and the complex conductivity.
