    • In this sense, the (antiferromagnetic) (Formula presented) chain is exceptional; it always satisfies (Formula presented) for all magnetization and lies in the region of unconditional localization. The case with (Formula presented) is in a sense marginal

    • The so-called flow equation for the renormalized coupling (Formula presented) [see Eq. (2) of Ref. 36] is replaced by (Formula presented)and an argument similar to that given in Ref. 14 leads to the conclusion that the system enters the random-singlet phase. Recall that special cases with (Formula presented) and 1 correspond to the model treated in Refs. 14 and 36, respectively

    • At least for multicomponent models known so far, there is always a region where a description based on the single-component TL model is valid. For such a region, we can still use the method presented here
