General holographic superconductor models with Gauss-Bonnet corrections

Abstract

We study general models for holographic superconductors in Einstein-Gauss-Bonnet gravity. We find that different values of Gauss-Bonnet correction term and model parameters can determine the order of phase transitions and critical exponents of second-order phase transitions. Moreover we find that the size and strength of the conductivity coherence peak can be controlled. The ratios $\omega_g/Tc$ for various model parameters have also been examined.
