From: Feshbach hypothesis of high-Tc superconductivity in cuprates

Fig. 6

We show the form factor \({{{{\mathcal{M}}}}}_{2}({{{\bf{k}}}})\) for hole doping in cuprate superconductors (\({t}^{{\prime} }/| t| < 0\)) for \(| {t}^{{\prime} }/{J}_{\perp }|=0.05,\,0.1,\,0.2\). The hole pockets (dashed lines) correspond to the single hole magnetic polaron dispersion with t/J = 10/3110 at relatively large doping δ = 15%.
