Figure 8: Plot of the time evolution of the 2D discrete system Eqs. (10–11) with σ = 0 (panels (a,c,e)) and the 1D LS equation (39) with σ̃ = 0 (panels (b,d,f)), shown in terms of |bm0(z)| (at the edge). The parameters for panels (a–b) agree with Fig. 5(a) with ν = 0.1. The parameters for panels (c–f) agree with Fig. 9(a) with (ω0, ν): (c,d) (3π/8, 0.1); (e,f) (5π/8, 0.1). The edge state persists over a long distance. Periodic boundary conditions in m are used.
