    • l+i which is often discussed in the context of isotropic spin systems: The vector chirality changes its sign under the parity operation but is invariant under the time-reversal operation whereas the scalar chirality changes its sign under both operations.

    • The string-correlation functions for j = 0.680 and 0.700 in Fig. 2(b) and for d = 0.80 and 0.70 in Fig. 4(b) seem to be bent downward for r ≳ 40. However, I note that the m convergence of the data for r ≳ 40 has not been achieved yet and the string correlation is enhanced as m increases. Thus, from the behavior of the string correlation for r ≲ 40 where the m convergence is almost achieved, I consider that the string correlations for the above j's and d's exhibit an algebraic decay and the bend-downward behavior observed for larger r is an artifact due to the truncation error eventually vanishing in the limit m → ∞.

    • note
    • Since the system in the DH phase can be described as two Haldane subchains, one might expect that the string correlation function on each subchains can be the order parameter of the phase. Contrary to the naive expectation, however, the string correlation on a subchain' does not exhibit a finite LRO but decays exponentially (see refs. 17 and 18).
