Superconductivity and doping on oxygen in the three band model

Recent experimental results - using NMR measurements - have shown, across the cuprates [1], that the maximum critical temperature is much more strongly correlated with doping on the oxygen than with total doping. Using the CDMFT approximation and a finite temperature CT-HYB impurity solver, we investigate the phase diagram of the three-band Hubbard model in order to reproduce those results with theoretical means. Although the correlation is not perfect, we found such a trend, first focusing on the superconducting order-parameter and then on the critical temperature. We also discuss correlations between the spin susceptibilities and order parameter and a regime of parameters with a coexistence between pseudo-gap and superconducting phase.
