Holographic Superconductors with the General RF² type Couplings

Original · EN

We explore the effects of the general non-minimally coupled RF²-type couplings on the holographic s-wave superconductors numerically in the Schwarzschild-AdS background. We calculate the condensation and conductivity of the model for the coupling parameters a₁ and β. 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 ωg/Tc ≈ 8. Moreover the smaller β and a₁ cause to gradually stronger and narrower coherence peak.
