Abstract

We explore the effects of the general non-minimally coupled [Formula: see text]-type couplings on the holographic s-wave superconductors numerically in the Schwarzschild-anti-de Sitter (AdS) background. We calculate the condensation and conductivity of the model for the coupling parameters a1 and [Formula: see text]. We obtain that the bigger deviations of the parameter a1 from the minimal case lead to the larger deviations of the gap frequency from the universal value [Formula: see text]. Moreover, the smaller [Formula: see text] and a1 cause to gradually stronger and narrower coherence peak.
