Abstract ：We investigate the effect of the RF 2 correction on the holographic superconductor model in the background of AdS black hole, where R is the Ricci scalar of spacetime and F 2 =Fμν Fμν is the Maxwell field strength. We observe that, similar to the effect caused by the Weyl correction, the higher RF 2 correction term can make it easier for the scalar operator to condense and result in the larger deviation from the expected relation in the gap frequency. However, we find that the condensation gap becomes larger as the RF 2 correction term increases, which is in strong contrast to the influences of the Weyl correction and Gauss–Bonnet correction.
