- Because the t-J and Hubbard models are related in the strong coupling regime through a canonical transformation, ℋt-J ≈ eiSℋHube-iS,36 in which S is given as Σ〈ij〉σ -it/U [ni-σ(1-n j-σ)ciσ† cjσ(1-ni-σ) ciσ†cjσ] the expectation values of the t-J model with respect to ΨG are approximately equivalent to those of the Hubbard model with respect to e-iSΨG. When one expands e -iS, the first-order part (∼t/U) of e -iSΨG broadly corresponds to ℘QΨG. Thus, the favorable fe

- It is difficult to estimate proper values of Z as a function of U/t with a finite-sized system, in the case that the position of the quasi-Fermi point moves and crosses a k point, when U/t is varied. As an example, we show the case of t′/t = 0.4 and L = 12 in Fig. 6, where the data for U/t = 6.5 deviates to some extent. For this parameter set, we find the quasi-Fermi point to shift in the nodal direction in Fig. 5(a).

- Generally, as system size decreases, the critical behavior near a phase transition tends to be less sharp, because a transition, in a strict sense, takes place only for Ns → ∞. For instance, the curve for t′, 0 and L, 10 in Fig. 8 (open square) is relatively smooth, whereas the curve for L, 16 seems to have an obvious jump. Thus, one must necessarily check system-size dependence to treat a phase transition

- The effect of difference (i, namely of t″/t, must be slight, because, according to Fig. 2 in ref. 23, the optimized |t″/t| is small both for the conductive (U/t ≲ 8.5) and insulating (U/t ≲ 8.5) phases. The effect of difference (ii, namely of putting μ′, μ in ΨLiu, manifests itself to some extent, because, as in Figs. 4(d) and 4e, the optimized values of μ and μ′ are quite different, especially in the insulating phase. Thus, it is possible that ΨLiu becomes quantitatively worse than ΨdQ for U ≲ Uc; better results would be obtained, if μ′, 0 is used instead of μ′, μ in ΨLiu

- In ref. 23, the system-size dependence of the gap parameter Δ0/t* for U/t, 9.5 (in the insulating regime) is shown in the inset of Fig. 1. Because the finite Δ0/ t* does not necessarily indicate the realization of SC, as we have mentioned, it is useless to check whether Δ0/t* remains finite for L → ∞, in order to determine whether or not SC arises
- 0/t* remains finite for L → ∞, in order to determine whether or not SC arises.
