Free energies of the two-scale periodic structures in the infinite-c LP model: in panel (a), with q = k4, the square superstructure dominates when −0.09205 [\lesssim \,\epsilon \,\lesssim] 0.7689. In panel (b), with q = k6, the hexagonal superstructure dominates when −0.1143 [\lesssim \,\epsilon \,\lesssim] 2.074. Finally, in panel (c), with q = [k_\infty], the lamellar superstructure dominates when [\epsilon \gtrsim] −0.06904. The two-scale superstructure always has a lower free energy than its single-scale analogue. The gray region is the same as in Fig. 4[link].
