Conductivity of holographic superconductors in Born–Infeld electrodynamics

Abstract

In this paper, we have analytically computed the conductivity of holographic superconductors in the framework of Born–Infeld electrodynamics taking into account the backreaction of the matter fields on the bulk spacetime metric. The effect of the Born–Infeld electrodynamics is incorporated in the metric. The band gap energy is found to be corrected by the backreaction and Born–Infeld parameters. The conductivity expression is then compared with that obtained from a self-consistent approach.
