note

In the cases of δ ≠ 0 a reduced Brillouin zone of [-π/2, π/2] should be used. However, since the intensity is not symmetric with respect to π/2, we use the original zone for comparison with undimerized cases.

As for [3], the divergence at q = π of S(q) tends to be suppressed by δ. However, δ never enhances the intensity partially for the lower edge of q ∼ π/2.
