    • For the zero-field case, the results of Ref. imply the antiferromagnetic ("up-up-down-down" type) order for β □ -3 and Δ>1. We have not attempted to make a connection to these results as our key interest is in the finite magnetization case, where the antiferromagnetic order is already destroyed.

    • The error bars in the finite-size DMRG results for the chiral order parameter κ02 in Figs. are crude estimates reflecting only the degree of asymptotic "flatness" of the chiral correlators like shown in Fig. (larger error bars imply that there is still a nonzero slope at large distances). Those error bars are thus just the measure of the strength of proliferation of the boundary effects into the bulk, and do not include any uncertainties related to the finite-size effects.

    • The reason is that a too small ξ effectively introduces a gap in the symmetric sector, which kills the twist term (Ref.) and prevents the emergence of chirality.
