A Comment on the Letter by V. G. Rousseau and P. J. H. Denteneer, Phys. Rev. Lett. 102, 015301 (2009).

Figure 1

Atom-molecule correlator for a $L=100$ chain with the following parameters: $(D/t_a,\mu /t_a)=(3,8.6)$ (squares), (7, 9.6) (circles), and (13, 10.6) (diamonds). The other parameters are $U_a=8t_a$, $U_{am}=12t_a$, $U_m=\infty$, $g=0.5t_a$, and $t_m=0.5t_a$. According to Fig. 10 of Ref. 3 all three parameter sets should give a SM phase.
