    • However the reader should be aware that HH model is presumably not the best candidate to address the physics of cuprate superconductors, at intermediate and large electron-phonon coupling producing bipolarons with extremely large effective mass (Ref, 19). Models with longer range electron-phonon interaction (Ref. 24) are believed to be more realistic for describing cuprates.

    • Notice that the total probability to have the electrons at the distance r from each other is C(r) times the number of sites situated at the relative distance r. Therefore, in Fig. 8, we plotted 4 × C(1) and 4 × C(2) which represent the probability to have the electrons on nearest and next-nearest neighbor sites, respectively.

    • In Figs. 9(b) and 9(c) small jumps in the correlation function at some particular values of r (for example between r=9 and r =10) are observed. This indicates that our projected state has a small amount of d-wave character, as explained in Fig. 10 and the related text paragraph.
