Model-mapped random phase approximation to evaluate superconductivity in the fluctuation exchange approximation from first principles

Hirofumi Sakakibara, Takao Kotani

We have applied the model-mapped RPA [H. Sakakibara et al., J. Phys. Soc. Jpn. 86, 044714 (2017)] to the cuprate superconductors La2CuO4 and HgBa2CuO4, resulting two-orbital Hubbar…
