Bright Solitons in a -Symmetric Chain of Dimers

Figure 1

Eigenvalues of intersite soliton I with , (a, b) and (c, d). Dots are from the numerics and solid lines are the asymptotic approximations in Section 4.2.1. The collection of dots forming black regions in the right column corresponds to the continuous spectrum.
