Query: Gauss-Bonnet holographic superconductors in exponential nonlinear
  electrodynamics   The low-energy limits of the string theory lead to the higher-order curvature
corrections for Einstein gravity. Also, they give the higher-order derivative
corrections for the Maxwell or linear electrodynamics, which suggests the
nonlinear electrodynamics. Inspired by this, in this paper we investigate
$d$-dimensional holographic superconductors in the probe limit in the framework
of Einstein-Gauss-Bonnet gravity and exponential nonlinear electrodynamics.
Based on the Sturm-Liouville eigenvalue method, we compute the critical
temperature, the condensation value, and the critical exponent. It is observed
that the critical temperature decreases when the Gauss-Bonnet (GB) parameter or
the nonlinear parameter increases, but it increases with the higher dimension
of the spacetime at the efficiently low charge density. In addition, we found
that the condensation value becomes larger as increasing the GB parameter, the
nonlinear parameter as well as the spacetime dimension. Finally, we calculate
the optical conductivity and study the effects of the GB term and exponential
nonlinear electrodynamics on superconducting energy gap.
