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 CuO₂ 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.
