This aspect has been discussed in various papers. In the general case of the commensurate-incommensurate transitions see for instance F. D. M. Haldane, P. Bak and T. Bohr, Phys. Rev. B28, 2743 (1983), or B. Horovitz, T. Bohr, J. M. Kosterlitz and H. J. Schulz, ibid. 28, 6596 (1983). Specifically for fermionic models see Ref. 11 or M. Mori, H. Fukuyama and M. Imada, J. Phys. Soc. Jpn. 63, 1639 (1994).
