    • note
    • In fact, we can determine the critical point without twisting the boundary conditions, but the excitation energies become higher and the finite-size effect becomes larger. The elimination of the charge excitation is also important in the identification of the universality class of the transition.

    • note
    • In contrast to the spin-gap phase boundary, the finite-size effect of the phase-separation boundary is large, and its systematic evaluation is difficult, so that the remaining ambiguity should be considered.
