Holographic superconductors with the general RF2-type couplings

We explore the effects of the general non-minimally coupled RF2-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 a(1) and beta. We obtain that the bigger deviations of the parameter a(1) from the minimal case lead to the larger deviations of the gap frequency from the universal value w(g)/T-c approximate to 8. Moreover, the smaller beta and a(1) cause to gradually stronger and narrower coherence peak.
