    • A second observed peak around hbar ω apeq21.4 eVapeq2 11 J (cf. Ginder et al. [Ref. 7, d)], not shown in Fig. 1(b) could be due to dopant induced, local Cu-O charge transfer string excitations [cf. Ref. 3(b) and, ] which arise in the full three-band model, but are eliminated from our strong-coupling models.

    • On a finite lattice with periodic boundary conditions, ID, evaluated at p = k0, is not guaranteed to be non-negative, since the allowed discrete wave vectors knu under periodic boundary conditions need not coincide with the minimum p0 of the continuously defined quasiparticle band E0( p,S). However, for N -> inf, we have |k0- p0| -> 0 and hence ID>= 0.

    • The local ZR Cu-O triplet state (cf. Ref. 9) couples to the triplet excitations of the AF spin background and can thus form total spin eigenstates which are accessible from the ground state by optical transitions, i.e., without change of total spin quantum numbers.
