Pairing interaction near a nematic QCP of a 3-band CuO${}_2$ model

Abstract

Here we calculate the strength of the $d$-wave pairing and the $k$ dependence of the gap function associated with the nematic fluctuations of a CuO${}_2$ model as the doping $p$ approaches a quantum critical point. Higher order $d$-wave harmonics contribute to the $k$ dependence of the resulting superconducting gap function reflecting the longer range nature of the nematic pairing interaction.
