Figure 11

(a) Energies of the dominant MIR peak (solid line with circles) and low-energy peak (dashed line with squares) of the t-J-H model versus . Energies of the dominant peaks of the Holstein model for (dashed line) and for (solid line). (b) OC of the t-J-H model (solid line) and effective Holstein model with (dashed line). Both OC are for . (c) and (d) Ratio of the effective coupling constants on doping (or real concentration of the hole in plain for YBCO [244]) and that at almost zero doping. Effective is determined by the fit of the MIR position at given doping.
